According to the reference manual the overdrive should be enabled after
setup of the sysclock (HSE or HSI) and enabling the PLL (PLLON).
The flash latency should be enabled after the PLL has been turned on,
but before switching the system clock to the PLL.

This commit follows the parent commit work.
This commit introduces the following major changes.
1. Move all directories and files in 'include/zephyr/arch/arm/aarch32'
to the 'include/zephyr/arch/arm' directory.
2. Change the path string which is influenced by the changement 1.

Warning callback by default is configured to happen
at the same time as reset, which results in unexpected
behavior from the point of view of Zephyr API. Return
-ENOTSUP from install_timeout if trying to set up
callback with 0 warning time, and add kconfig to configure
the warning time.

LL_RTC_Init() internally uses LL_RTC_EnterInitMode() wich uses a blocking
while loop. This rewrite uses the less CPU time wasteful local
rtc_stm32_enter_initialization_mode() instead. As a side effect
LL_RTC_InitTypeDef in rtc_stm32_config is not needed anymore.

Calling LL_RTC_Init causes the RTC to stop while being configured thus
inducing time drift. This commit avoids doing it at each reset if the RTC
is already properly configured.

ST7735S requires the COLMOD command be repeated as part of writing

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

for using this feature.
For example.

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.
