9.2. This includes changes done to display and input driver initialization
and draw buffer handling.

Add a void *user_data pointer to the input callback structure. This is
useful for driver to get back the driver data structure and avoid
defining wrapper functions.

https://github.com/zephyrproject-rtos/zephyr/pull/70541 has an
issue where if the screen has been rotated, values calculated if
invert-x or invert-y are set will be overwritten.
This breaks the adafruit_2_8_tft_touch_v2 touchscreen as the
display is rotated by 90 degrees but uses invert-x and invert-y.
This change makes the invert-x and invert-y options independent
of screen rotation.

This patch fixes two issues in the coordinate handling of the
`zephyr,lvgl-pointer-input` compatible:
- If the swap-xy flag is set the coordinates need to be swapped even
before the sync event is received.
- The coordinates are stored into an additional variable instead of the
pending_event. This is done to prevent the double inversion for touch
release events.
Resolves issue #70539.

Introduces a Kconfig symbol `LV_Z_LOG_LEVEL` because contrary to Zephyr the
numerical value of log levels in LVGL increases with severity. Also support
for the `LV_LOG_LEVEL_USER` is added.
Resolves issue #64351.

Removes the pseudo device prerequisite that the LVGL setup routine has been
executed before initialization. The pseudo devices are now registered at
the end of the LVGL setup routine, the driver is not concerned with
configuring the devices anymore. This also removes the need for enforcing
certain priorities within the same init level.
This resolves issue #62753.

Add the scaffolding to create input lvgl pseudo devices which route zephyr
input_event to their lvgl `indev` equivalent. As a first cut also add a
`zephyr,lvgl-pointer-input compatible which can be a drop-in replacement
for the existing kscan solution.
