The NRF_TWI_Type struct doesn't have an homogeneous layout between
nRF51/52 series. This patch tries to select the right layout based on
selected SoC.

The incorrect sequence will cause the thread cannot be aborted in the
ISR context. The following test case failed:
tests/kernel/fatal/exception/kernel.common.stack_sentinel.
The stack sentinel detects the stack overflow as normal during a timer
ISR exit. Note that, currently, the stack overflow detection is behind
the context switch checking, and then the detection will call svc to
raise a fatal error resulting in increasing the nested counter(+1). At
this point, it needs a context switch to finally abort the thread.
However, after the fatal error handling, the program cannot do a context
switch either during the svc exit[1], or during the timer ISR exit[2].
[1] is because the svc context is in an interrupt nested state (the
nested counter is 2).
[2] is because the current point (after svc context pop out) is right
behind the switch checking.

The temp val should be uint64_t in read_sysreg64 instead of uint32_t.
The incorrect type uint32_t will cause an issue:
mrrc instruction needs 2 registers when reading from a 64-bit system
register. The type uint32_t tells GCC only to save/restore one register,
so after the mrrc is executed, the other would clash.

This is painful. There is no way for u-mode code to know if we're
currently executing in u-mode without generating a fault, besides
stealing a general purpose register away from the standard ABI
that is. And a global variable doesn't work on SMP as this must be
per-CPU and we could be migrated to another CPU just at the right
moment to peek at the wrong CPU variable (and u-mode can't disable
preemption either).
So, given that we'll have to pay the price of an exception entry
anyway, let's at least make it free to privileged threads by using
the mscratch register as the non-user context indicator (it must
be zero in m-mode for exception entry to work properly). In the
case of u-mode we'll simulate a proper return value in the
exception trap code. Let's settle on the return value in t0
and omit the volatile to give the compiler a chance to cache
the result.

Stop using &_kernel as this is not SMP friendly. Let's use s0 (after
preserving its content) to hold ¤t_cpu instead so it won't have
to be reloaded each time it is needed. This will be even more relevant
when SMP support is added.

Rely on mstatus rather than thread->base.user_options since it is always
up to date (updated by z_riscv_switch) to simplify the code and be SMP
proof. Also carry over SF_INIT to the mstatus being restored in case
it was changed in the mean time.

The minimum stack alignment is 16. Therefore, the stack space to store
a struct __esf object must be rounded up to the next 16-byte boundary.
It is not sufficient to do the rounding on the __z_arch_esf_t_SIZEOF
definition. When the stack is constructed in arch_new_thread() it is
also necessary to do the rounding there too.
Let's make the structure itself carry the alignment attribute instead to
make it work in all cases.
While at it, remove the unused _K_THREAD_NO_FLOAT_SIZEOF definition.

Same rationale as preceding commit. Let's create pseudo-instructions in
assembly scope to make the code more uniform and readable.
Furthermore the definition of COPY_ESF_FP() was wrong as the width of
floating point registers vary not according to CONFIG_64BIT but
CONFIG_CPU_HAS_FPU_DOUBLE_PRECISION. It is therefore wrong to use
lr/sr (previously RV_OP_LOADREG/RV_OP_STOREREG) and a regular temporary
register to transfer such content.
Note: There are far more efficient ways to copy FP context around but
such optimisations will come separately.

Those are prominent enough that having RV_OP_LOADREG and RV_OP_STOREREG
shouting at you all over the place is rather unpleasant and bad taste.
Let's create pseudo-instructions of our own with assembler macros
rather than preprocessor defines and only in assembly scope.
This makes the asm code way more uniform and readable.

The thread->base.user_options field is an uint8_t. Access it using lb.
A "copy" of it is made into __esf.fp_state. Make that field an uint8_t
too and access it with lb/sb.
_callee_saved.fcsr is an uint32_t. Access it with lw/sw.
Ditto for is_user_mode.

The header file radio_df_vendor_hal.h was conditionally copiled in.
There were a dependency on a CONFIG_BT_CTRL_DR. The dependency is
removed because radio_df_vendor_hal.h and radio_df.h hasn't got any
DF related type dependencies. What more it allows to use IS_ENABLED
for code that uses types and functions defined in radio_df.h.

The EVENTS_CTEPRESENT is available when radio peripheral has
direction finding support. The event is set if received
PDU has CTEInfo and there were collected IQ samples during
CTE reception.
The event should be cleared always when other events are cleared.
That guarantees that the event is not set when use of radio for
following activities.

The radio_df_cte_ready function returns state of EVENTS_CTEPRESENT.
The function may not be used in create_iq_report function, because
it is called after lll_isr_rx_status_reset. The lll_isr_rx_status-
_reset clears EVENTS_CTEPRESENT value.
The result of this calls chain is lack of IQ sample report no matter
if the PDU has CTEInfo and radio has collected IQ samples.
To fix the problem, state of EVENTS_CTEPRESENT has to be get when
e.g. rssi_ready is get.
