Drop a bunch of display functions that only return "not supported", the
display API already handles these by checking for NULL API function
pointer.

`spi_is_ready` function is being deprecated in favor of
`spi_is_ready_dt` so let's replace the old usage in the tree.

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Simplify driver implementation by using gpio_dt_spec. As a result, the
driver data structure has become unused and so removed.

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.
