drm/vc4: Add FKMS as an acceptable node for dma ranges.

raspberrypi inclusion
category: feature
bugzilla: 50432

--------------------------------

Under FKMS, the firmware (via FKMS) also requires the VideoCore cache
aliases for image planes, as defined by the dma-ranges under /soc.

Add rpi-firmware-kms to the list of acceptable nodes to look for
to copy dma config from.
