Gabriel Valcazar 191f891f6c lvgl: clean up configuration options
Remove options that aren't supported in v9.3.0 (LV_MEM_CUSTOM and
LV_TICK_CUSTOM_*) and move the lvgl-demo's default values to lv-conf.inc so
they can be changed via local.conf

Gabriel Valcazar de238b6d81 lvgl: lvgl-demo: rework recipe to include wayland backend support
Rework our customizations and apply them as full files instead of patches to
make it easier for users to inspect.

Instead of having one cmake file for all backends, provide a separate file for
each backend and select it dynamically based on the selected backend. To do
this, create a new LVGL_BACKEND variable in lv-conf.inc.

While at it, increase the demo's memory from 256 KiB to 2 MiB to ensure that
the wayland flavor of the demo works properly.

Gabriel Valcazar e3df152ccd lvgl: remove support for the SDL backend
This backend depends on libsdl2, a library we don't include in our default
images. Even when this library is included, the LVGL demo doesn't work properly
when using the SDL backend on any of our platforms, so remove it.

Gabriel Valcazar c360c9b757 Revert "lvgl-demo: remove vestigial Wayland logic"
We're going to be adding support for LVGL's wayland backend in the following
commits, so recover the initscript logic that ties in with said backend

This reverts commit 21d9c4f17b.

Gabriel Valcazar 55d58ea814 lvgl-demo: make HDMI the default display for ccimx6/ccimx6qp
In these platforms, /dev/fb0 corresponds to the LVDS display, so change the
demo's output framebuffer to /dev/fb3 to use the HDMI display instead.

Gabriel Valcazar 289a6e5e09 lvgl: move lvgl-demo-init modifications to their corresponding recipe
lv-conf.inc is a general configuration file, meant for any LVGL application,
while lvgl-demo_9.3.0.bb is the recipe for our example demo. Make sure any
modification made to the demo or its initscript is made in its corresponding
recipe.

This is cosmetic, no functional change.

Gabriel Valcazar 21d9c4f17b lvgl-demo: remove vestigial Wayland logic
In platforms that support wayland/xwayland, dey-image-lvgl images have most
weston/wayland packages removed from the filesystem, save for the main wayland
package (because DISTRO_FEATURES still contains "wayland"). Because of this,
the wait_for_wayland() function is called in lvgl-demo-init, but the wayland
display never gets created, causing the function to time out after 20 seconds.
Get rid of this check to have the lvgl-demo launch as soon as possible.

While at it, get rid of other wayland-related logic, since we only use LVGL's
drm or fbdev backends at the moment.
