arm64: dts: ti: am62x: am62p: Remove fb reserve and keep simplefb disabled
U-boot now supports dynamic update of simple-framebuffer region and
framebuffer reservation for AM62x and AM62p platforms if bootloader splash
screen is enabled.
U-boot detects simple-framebuffer stub in device-tree (which is kept as
disabled by default) updates it with framebuffer meta-data (viz. video
format, framebuffer address) and enables it before booting Linux.
In case simple-framebuffer stub is not preset in device-tree (for e.g.
when user wants to keep bootloader splash active till OS bootup without
displaying anything else as an intermediate), U-boot still updates the
device-tree with framebuffer reservation to preserve the splash-screen till
OS bootup.
