ea717bba21 drivers: display: st7735r: support ST7735S
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.

Set the inverted value of pixel format setting in MADCTL register to

89a4f36fc8 device: remove inclusion of pm/device.h
The device PM subsystem _depends_ on device, not vice-versa. Devices
only hold a reference to struct pm_device now, and initialize this
reference with the value provided in Z_DEVICE_DEFINE. This requirement
can be solved with a forward struct declaration, meaning there is no
need to include device PM headers.

8b8e8f99ba display: introduce CONFIG_DISPLAY_INIT_PRIORITY
This introduces a new kconfig CONFIG_DISPLAY_INIT_PRIORITY
to specify the initialization priority for display devices.
Most of the display devices are using APPLICATION and
CONFIG_APPLICATION_INIT_PRIORITY which is not entirely
appropriate for devices. Due to linking order, the display
device may be initialized after application code at same
init level and priority. This results in the display device
not ready to be used for application code. So this kconfig
option allows the display devices to be initialized earlier
if needed.

For the drivers using CONFIG_APPLICATION_INIT_PRIORITY,
they have been changed to use CONFIG_DISPLAY_INIT_PRIORITY
instead.

Note that the default value for CONFIG_DISPLAY_INIT_PRIORITY
is the same as CONFIG_APPLICATION_INIT_PRIORITY at 90 to
avoid any functional changes.

7ccc1a41bc pm: use actions for device PM control
Instead of passing target states, use actions for device PM control.
Actions represent better the meaning of the callback argument.
Furthermore, they are more future proof as they can be suitable for
other PM actions that have no direct mapping to a state. If we compare
with Linux, we could have a multi-stage suspend/resume. Such scenario
would not have a good mapping when using target states.

The device PM subsystem already holds the device state, so there is no

not safe, but the same applied to the previous implementation. This
