Several drivers checked for the presense and availability of data cache
through Kconfig symbol. This is supported according to the current
documentation, but the symbol DCACHE masks two types of cache devices: arch
and external caches. The latter is present on some Cortex-M33 chips, like
the STM32U5xx. The external dcache is bypassed when accessing internal
SRAM and only used for external memories.
In commit a2dd232410 ("drivers: adc: stm32: dma support") the rationale
for gating dcache for adc_stm32 behind STM32H7X is only hinted at, but
reason seems to be that it was the only SOC the change was tested on. The
SOC configures DCACHE=y so it is most likely safe to swap the SOC gate for
DCACHE.
The DCACHE ifdefs are now hidden inside the shared stm32_buf_in_nocache()
implementation.

When the device was suspended and the pin level changed during
that time, the pin level of course isn't updated in the pins cb_data.
Once the device is resumed, this leads to potentially having
a wrong value in the pin state data leading to swallowing the first
event due to comparing the stored level vs. the new level before
reporting.
Also added some `const`s and deleted an unused struct element.

'timings' is an array of 'struct i2c_config_timing' (3 x uint32_t).
'i2c_timings_##index' is an array of uint32_t (hence the cast when it
is assigned to 'timings'). Therefore 'ARRAY_SIZE(i2c_timings_##index)' is
off by a factor 3 when used for n_timings.

The EC timer runs at 9.2 MHz, which leads to a non-integer number of
ticks per microsecond. This causes slight overestimation when delays
are computed using whole ticks (e.g., using 10 ticks for 1 µs).
To address this, the busy wait calculation is adjusted with a
compensation factor to minimize cumulative timing error over time.

The typical way of calling INPUTMUX_AttachSignal() is to
bracket it around INPUTMUX_Init() and INPUTMUX_Deinit()
calls because we can reduce power consumption by not
keeping the interface powered when not changing INPUTMUX.
This driver was violating that convention, which caused
it to not coexist well with other code that followed the
usage convention because the INPUTMUX might be initialized
or not depending on execution order with the other modules.

This patch enhances the power management capabilities of the Intel ADSP
by ensuring that power gating states are appropriately managed based on
core activity. It prevents the primary core from entering power gating
if secondary cores are active and re-enables power gating when all
secondary cores are off, using pm_policy_state_lock_get and
pm_policy_state_lock_put functions.
The Sound Open Firmware (SOF) project currently uses a custom power
management policy to achieve these effects. With this patch, the default
power management policy can be utilized, allowing the option to disable
the custom policy while maintaining system reliability and performance
across different core states.
