Subject: [PATCH] ARM: bcm2835: Add the DPI hardware to the device tree.

It's currently marked disabled, as it's not useful without a panel
associated with it and the GPIO pins routed to ALT2.

This patch got misplaced as part of the original VC4 DPI work (which
included the binding). I've got a full branch demoing a panel at
https://github.com/anholt/linux/commits/drm-vc4-dpi

Eric, do you want me to apply that directly to my upcoming ARM SoC pull
request (next couple of days)?
