Instead of relying on Kconfig, use dt inputs to configure LPTIM domain
clck (LSI/lSE).
Clock control dedicated APIs are used for configuration and get the
frequency of domain clock in use.
Constants macros used previously to store frequency and time base are
converted to static global variables.
Some code was set up specifically to keep compatibility with targets
that still use Kconfig to configure domain clock. This will be removed
after a deprecation period.

i2c_transfer_async is the asynchronous version of i2c_transfer where
the completion of the transfer is notified to the caller using a callback.
This can be used in conjuction with the common callbacks and datatypes
in async.h for directly doing an async transfer with an IPC object
to notify a thread.

STM32h7 pllout frequency calculation overflows. In the
worst case pllsrc_freq can be 50Mhz and plln_mul 512 which will cause
an overflow of the intermediate result which leads to wrong frequency
returned. As no intermediate result can be bigger than 960MHz only the
order of operations is changed.

The current atmel sam flash driver was develop based on the cortex-m7
version of smart arm microcontroller. The driver support write
protection and cache functions which is not supported by other cortex-m
variants. This fixes current driver implementation and devicetree
entries for all sam variants.
Notes:
* The cortex-m3 doesn't have support erase pages flash command and
because of that the driver still not not compatible. Keep it disabled
until a patch be send. The hwinfo driver is not affected by this
restriction.
* The sam4l variation requires a specific driver because uses another
flash controller (flashcalw). Added another compatible to
differentiate and keeped node disabled until a driver be available.

This is a bug fix. A pointer to the spi configuration is not saved when
the spi driver is configured for slave operation and it can lead to
runtime errors.

Now that entropy drivers are enabled based on devicetree
we need to remove any cases of them getting enabled by
Kconfig.defconfig* files as this can lead to errors.
