Adds driver for pwm on xmc4xxx using Capture Compare Unit 8 (CCU8)
module. There are two CCU8 nodes with each one having four slices.
Each slice has two output channels.
Unlike CCU4, this module can generate complementary high-side/low-side
signals for each output channel. A variable dead time can be added
during the off to on transitions to make sure that the
high-side/low-side signals are not on at the same time.

Adds driver for pwm on xmc4xxx using Capture Compare Unit 4 (CCU4)
module. There are four CCU4 with each one having four channels
Thus it's possible to have up to 16 pwm output signals. The output of
each channel can only be connected to a specific port/pin. The possible
connection and gpio configurations are defined using pinctrl.
The CCU4 module also has a capture mode. Capture support will be added
in the future.

- use CONFIG_HAS_HW_NRF_* symbols consistently in nRF multi-instance
drivers when creating particular driver instances
- remove unnecessary hidden Kconfig options that indicated the type of
peripheral to be used by a given instance (e.g. SPI, SPIM, or SPIS)
and enabled proper nrfx driver instance; instead, use one option per
peripheral type and include the corresponding shim driver flavor into
compilation basing on that option (not the one that enables the nrfx
driver as it was incorrectly done so far in some cases)

Updated the driver to support low power mode.
Introduced "enable-low-power" flag in device tree to
control(on/off) low power mode.
If flag added in DTS, during sleep BBLED will switch off the LEDs.
Otherwise BBLED will continue the configured blinking pattern on LEDs.

Current implementation of `nrfx_pwm_stopped_check()` doesn't work
as expected when user doesn't provide event handler.
Workaround for that is to use low level function for checking whether
STOPPED event arrived.
The workaround should be removed when `nrfx_pwm_stopped_check()`
will contain needed functionality.

Some STM32 timers have more than one interrupt available.
When such timer is used it's likely that the first found interrupt
will not be the proper, 'cc' interrupt for input capture.
Existing implementation always connected the first irq, which worked
for timers with single, 'global' interrupt but broke input capture
for advanced timers with more interrupts.
Improve the IRQ connection logic by connecting the 'cc' interrupt
if it exists. Only if not found use the fallback mechanism of taking the
first index

pwm_set_wrap() sets the TOP value, not the number of cycles.
Counter will run from 0 to TOP inclusive, generating TOP + 1 cycles.
To get n cycles, we need to set TOP to (n - 1).

there was always one extra cycle.

Depending on the timing of the edges of the signal to be captured, a timer
overflow interrupt flag may appear in the same ISR as a channel event (1st
or 2nd edge capture complete) flag. Change the timer overflow math to
compensate the timer overflow count based on whether the channel event
happened before or after the overflow flag occured.
For continuous PWM period captures, only the very first edge of the first
period requires an interrupt to be captured. Subsequent "first edges" are
the same edges as the second edge of the previous period. Depending on the
timing of the captured signal, enabling the 1st edge interrupt in this case
can cause the overflow count for subsequent first edges to be captured at
the wrong point in time.

When pwm_it8xxx2_set_cycles() is called, we disable the pwm clock
at the beginning and enable it at the end, so there is a more than
1ms pwm low pulse when every time changing the cycle. The low pulse
would let some fans go to idle mode, so we don't gate the pwm clock.

By Starting the timer when period was set to 0, the SCTimer was giving
control of the pin back to the timer and over-riding the value written
to base->OUTPUT register. Consequently, the PWM timer was never
stopped and still using the previously configured period.
The PWM now correctly stops when setting the period to 0.
