Currently when the voltage measured on the rail after a set voltage
operation is out of margin an error is returned. Upon this error, no
further action is taken. This causes the framework to log an error,
while this is rather a driver expectation.

Manual testings have also shown that the threshold is probably too
tight as in some circumstances the deviation from the target reaches
30-35 mV.

Since no action is taken after the margin comparison, simply log the
fact from the driver itself and return FWK_SUCCESS, as the event has
been processed correctly.

The recent change of frequency unit from Hz to kHz has left one
set_rate call with the previous units, resulting in a failed frequency
change.

Align the remaining set_rate with the correct frequency unit.

The recent change to the standard library memory allocator has removed the
trapping mechanism that prevented the function to return a NULL pointer.
As some callers make the assumption that the pointer returned is always !NULL,
this may cause a NULL pointer dereference.

Reintroduce the trapping instead of returning a NULL pointer.

Furthermore, add a new fwk_mm_alloc_notrap() function to be used specifically
by fwk_io_vprintf() which handles the case for a null pointer.

Remove unused variables.

Introduces a basic Voltage Domain driver and a SCMI voltage domain
protocol driver. SCMI voltage domain protocol is introduced in SCMI
specification v3.

Module voltage_domain is a generic HAL for voltage domains, aka power
supply regulators drivers. Based on module configuration, the module
binds each element to the voltage domain backend driver thru a generic
driver interface:
- set & get config, using SCMI voltage domain configuration format.
- set & get voltage level, in microvolt (uV)

More recent versions of Doxygen now complain when multiple `\retval`
commands are found with the same return value. This commit fixes these
issues, replacing them instead with a single `\retval` containing a list
of possible reasons the function might return the value.

This commit replaces any instances of `@`-style Doxygen commands with
their `\`-style equivalents. This is done for consistency across the
codebase.

The `\sa` Doxygen command has been added to the Clang-Format
configuration to prevent it from reflowing see-also comments, which
often exceed the column limit due to referring to long URLs.
