ST7735S requires the COLMOD command be repeated as part of writing
pixels, otherwise it goes back to some kind of default which is likely
wrong.
ST7735S works correctly after this plus the previous two commits; tested
on STM32L462 + KD0096FM.

Reset the device on initializing if reset-node is available in dts.
`snps,desingware-i2c` does not define reset-node itself.
Add more of an element that inherits `reset-device.yaml` to
the `compatible` section to allow defining the reset-node
for using this feature.
For example.
```
compatible = "reset-device-inherit-node", "snps,designware-i2c";

Seems like the SSD1306 controller needs a bit of time after power up
before it can take i2c commands. This causes problems with
microcontrollers that have no other delays in the startup sequence, like
rpi_pico.
There's currently no good way of modeling this in Zephyr right now, and
there's also no clear indication of how much time the device needs in
the datasheet that I could find, but it seems like 10ms is enough for
that to start reliably so add a delay in the ssd1306 init function to
ensure that at least that time has passed from system power up.

This change allows to have GPIO interrupts configured
that will work while chip enters low power modes where
PD_COM is turned off.
PDC controller can wake up system on GPIO changes even when

Previously the pwm capture only support capturing on channel 1
and 2, because the slave mode controller was used, which uses
the signal TIxFP which is not available for channel 3 and 4.
This commit adds optional support for four channel capturing by
changing the method of capturing PWM signals to not use the
slave mode controller to reset the counter register. Instead the
counter is reset in the ISR. This will result in a slight loss
of accuracy but is still within an acceptable range.

This introduces PWM driver with supporting PWM output
APIs based on NXP S32 EMIOS peripheral. This supports
three mode: OPWFMB, OPWMCB and OPWMB.
OPWFMB uses internal counter, the new period and duty
cycle takes effect immediately.
OPWMCB and OPWMB use external counter as timebase, changing
PWM period at runtime will impact to all channels share the
same timebase. Also the new period and duty cycle take effect

This commit improves the usage of the bus pipe (connected
to UART) to only open it when the modem is actually
powered and ready, not when leaving the idle state. This
ensures the pipe is flushed before sending the init script,
and re-enables the UART driver if it is disabled due to
errors.
While building a test platform based on the nRF9160 and a
Quectel BG95, it was discovered that the nRF9160 correctly
throws UART errors if the RX is enabled while the UART RX
line is low (which was due to the modem being powered
down).
The improvements should also help help remove the
"<wrn> modem_chat: receive buffer overrun" warning which
would occur during startup as the pipe was opened, but
nothing was receiving the data, causing the buffer to
overflow.
