Similar to `stm32_ltdc_display_blanking_off()`, use local device variable
instead of accessing the config's structure member again.

Blanking On/Off calls should not return 0 when there is no panel
controller to forward them to, instead they should return ENOSYS to
signal to the application that they were not actually executed.
"device_is_ready" does check for null, but also for
"dev->state->initialized == false", so we need to isolate the
"dev == NULL" case.

Display is not working on STM32F429i-DISC1 board because
display_blanking_off() needs to be sent to ILI9341 device, but it's sent
to LTDC instead which does not implement it.
This patch adds a LTDC DT property that provides the pHandle of the
display's own controller so that display_blanking_off/on are forwarded to
it when they are called by an application.

As the display API now check against valid callback functions and
returns -ENOSYS (or equalent), there is no need to provide
such functions in the driver code

When backlight pin is not defined, a display suspend will cause
a crash since it looks at the wrong pin when deciding if
it exists.

The CMSIS module glue code was part of arch/ directory. Move it to
modules/cmsis, and provide a single entry point for it: cmsis_core.h.
This entry header will include the right CMSIS header (M or A/R).
To make this change possible, CMSIS module Kconfig/CMake are declared as
external, allowing us to add a new Zephyr include directory.
All files including CMSIS have been updated.
