The asserts and validation code were incorrectly mixing pitch and
width. These incorrect checks were preventing rendering code from
re-using a smaller section of a buffer allocated to fit the full
screen. We expect to be able to update a portion of the display from a
portion of the buffer, in which case pitch must remain the screen
width. Expecting x + pitch to be smaller than the screen width is
incorrect.

This allows to invert the display at runtime using the function
`ssd1306_set_pixel_format`. The current format is stored in the data
struct.
Also adjusted `ssd1306_get_capabilities` to return both supported
formats and the current one.
From the ssd1306 doc: 'In normal display a RAM data of 1 indicates an
"ON" pixel while in inverse display a RAM data of 0 indicates an "ON"
pixel.' Thus `PIXEL_FORMAT_MONO01 == SSD1306_SET_NORMAL_DISPLAY`.

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.

Fix usage of MIPI buffer descriptor in ili9xxx driver. Previously, the
buffer descriptor size was being set to display buffer size. For cases
where the write height/width was not equal to the size of the buffer, this
resulted in additional data being written that was not needed. To
resolve this, calculate the mipi descriptor buffer size in the driver
Also, remove the unconditional setting of mipi_desc.height, as this
would override the previous (correct) setting.

it should be set to 66mV (the default value)

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.
