The Raspberry Pi Foundation's firmware updates are shipping device
trees using the old string, so we'll keep recognizing that as this rev
of V3D. Still, we should use a more specific name in the upstream DT
to clarify which board is being supported, in case we do other revs of
V3D in the future.

VC4 is the GPU (display and 3D) present on the 283x.
Signed-off-by: Eric Anholt <eric@anholt.net>

v2: Sort by register address, mark HDMI as disabled by default in the
SoC file and enable it from -rpi.
v3: Add references to the pixel/HSM clocks for HDMI. Rename
compatibility strings and clean up node names.
v4: Fix comment marking pv0's interrupt as pwa2 instead of pwa0.
Rename hpd-gpio to hpd-gpios.
v5: Rebase on bcm283x.dtsi change, add v3d.
v6: Make HDMI reference the power domain.
v7: Fix the HDMI HPD gpios active value and HDMI enable for each RPI
board. Change V3D compatible string to 2835.
