Subject: [PATCH v3 7/7] ARM: bcm2835: Add VC4 to the device tree.

VC4 is the GPU (display and 3D) present on the 2835.

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.
