arm64: dts: meson-g12: add support for simplefb 



SimpleFB allows transferring a framebuffer from the firmware/bootloader
to the kernel, while making sure the related clocks and power supplies
stay enabled.

Add nodes for CVBS and HDMI Simple Framebuffers, based on the GXBB/GXL/GXM
support at [1].
