Allow STM32 I2C driver v2 to operate with DMA support even when
CONFIG_MEM_ATTR is disabled which happen when CONFIG_ARM_MPU is
intentionally disabled despite the CPU supports MPU.
By the way, remove a #ifdef directive on header files inclusion
that adds noise in the header file inclusion section without any
benefit.

Fix STM32 I2C driver to not call cache management related functions
when DMA is not used. This change fixes an issue introduced by
commit 42c3a78148 ("i2c: stm32: Add cache memory support"). The issue
makes boards embedding this driver with both CONFIG_I2C_STM32_V2_DMA
and CONFIG_ARCH_MPU disabled to fail to build with an error trace message
like the below:
.../i2c_ll_stm32_v2.c:701: undefined reference to `mem_attr_check_buf'

This commit provides an extension to the i2c_nrfx_twim driver.
It introduces possibility to acquire/release exclusive access to the
i2c bus. While the exclusive access to the i2c bus is acquired
you can access the underlying nrfx_twim driver directly.

On timeout, it's possible for the controller to be in a bad state.
This change initiates the transfer abort sequence which can recover

The i2c_transfer() API allows multiple msgs objects to be carried in a
transaction. After handling the current msgs object in the interrupt
context, the driver notifies the calling thread to buffer the next
msgs object and generate the Re-Start if required.
However, if the calling thread is preempted by higher priority threads,
the I2C transaction time may become non-deterministic (depending on the
execution time of higher-priority threads). This commits modifies the
driver to handle msgs objects entirely in the interrupt context to
improve the I2C transfer efficiency..

Since the RA2L1 uses the macro "ICU_EVENT" instead of
"ELC_EVENT" (which is currently used) to input into
the IELSR register, the ek_ra2l1 board cannot assign
any interrupts for any driver.
This commit aim to correct the Event macro to input correct
value for IELSR register on all the Renesas SoC by using
"BSP_PRV_IELS_ENUM" macro.

The Atmel SAM0 SoC enable peripherals clocks in distinct places: PM and
MCLK. The old devices had defined the peripheral clock enable bit at PM.
On the newer devices this was extracted on a dedicated memory section
called Master Clock (MCLK). This change excludes the dedicated bindings
in favor of a generic approach that cover all cases.
Now the clocks properties is complemented by the atmel,assigned-clocks
property. It gives the liberty to user to customize the clock source
from a generic clock or configure the direct connections.
All peripherals drivers were reworked with the newer solution.

Add support for the I2C_MSG_RESTART flag to be able to use a

instead of starting and stopping for each transaction in the chain.

RTIO correctly declares tx buffers as const, however, the
existing I2C API and NRFX (SDK) drivers don't. Therefor cast the
const buf to non-const when passing the tx buf to the twim driver
from the RTIO call to avoid the const warning.
The tx buffer is being treated as const data naturally in the
NRFX driver, its just not declared as such since we reuse the
buffer for both RX and TX data.
Alternatively the SDK and "shim" drivers built on top of it need
to be updated, which is quite a bit of work :)
