lvgl: Default to XRGB8888 DRM framebuffer

Browse Source 
The ARGB8888 framebuffer format for base canvas makes little sense
as the base canvas is unlikely to be transparent and require alpha.
Use XRGB8888 framebuffer format which is more widely supported by
DRM drivers as base plane pixel format.

This is identical to upstream fix for this issue which already landed:
c71e5f84bb
The upstream fix just never made it into the LVGL 9.0.0 for some reason,
an repeated upstream fix is being worked in now.
