In order to be consistent with what is possible in Devicetree, always
take a period in nanoseconds. Other scales or units may be specified by
using, e.g., the PWM_MSEC() macros (all of them converting down to
nanoseconds). This change then deletes the "_nsec" and "_usec" versions
of the pwm_set call.
Note that this change limits the period to UINT32_MAX nanoseconds,
~4.3s. PWM is, in generali, used with periods below the second so it
should not be a problem.

In a first place, the PWM API operates on "channels", not "pins". While
the API calls could have been changed by _channel, this patch takes the
approach of just dropping _pin. The main reason is that all API calls
operate by definition on a channel basis, so it is a bit redundant to
make this part of the name. Because the `_dt` variants of the calls are
going to be introduced soon, the change to `_channels` + `_dt` would
make API function names quite long.

SOCs using the EDMA IP that supported caching must locate EDMA transfer
control descriptors (TCDs) in non cacheable memory. For M7 cores, this
can simply use the "nocache" section. For M4 cores, where the nocache
section does not exist, the chosen SRAM section must be a tightly
coupled memory block which cannot be cached. Add a note to all boards

Align with other PWM drivers and treat the `pwm` parameter (described
ambiguously as "PWM pin") of the `pwm_pin_set_cycles` function as a PWM
channel, not an SoC pin. This will also make the driver consistent with
the `pwm-cells` property definition in the "nordic,nrf-sw-pwm" binding
and with related `DT_PWMS_*` macros.
The change described above requires also providing a way to specify
SoC pins that are to be assigned to the PWM channels. Hence, the commit
introduces in the "nordic,nrf-sw-pwm" binding the `channel-gpios`
property that replaces the `channel-count` one.

STM32H7 series offer alias addresses to access some registers that could
be accessed by the M4 core on dual core variants.
For instance RCC_AHB3ENR could be accessed at following offsets:
- 0x0D4: Accessible from both cores
- 0x134: Accessible from C1 (M7) core
- 0x194: Accessible from C2 (M4) core (if any)
For most single core H7 variants, the two first addresses were accessible,
but for some others (stm32h7ax/stm32h7bx), only the 'C1 accessible'
was available.
This fact used to be hidden by the use of LL API to access these registers,
providing the required abstraction (an mainly using the first alias
when possible to simplify implementation).

Instead of computing hclk freq use for flash latency setting after
setting the PLLs, do it right at the beginning of the function.
Indeed, first step of PLL configuration is to switch back sysclock
to HSI source (in case it was initially PLL).
In that case, flash latency is theoretically set in consistency with PLL
driver hclk. So we should "measure" hclk freq at that step rather than
once sysclock is back on HSI.
