rpi-base: Add missing overlay_map.dtb and vc4-kms-v3d-pi4.dtbo

Browse Source 
overlay_map.dtb arranges that when config.txt requests "vc4-kms-v3d"
the rpi4 will actually load "vc4-kms-v3d-pi4" and fixups like that.
It is present on the official distros, and must be put into the
overlays subdirectory in the boot partition.
For a detailed description of the overlay_map.dts file see:
  https://www.raspberrypi.org/documentation/configuration/device-tree.md#part2.2.10

vc4-kms-v3d-pi4 is required for the arm based kms driver on the rpi4.
