dt-bindings: display: bcm2835-v3d: Add an optional reset line

Browse source

The BCM2835 power management block drives a reset line for the V3D block
that is independent of the graphics power domain, allowing the GPU to be
reset without power-cycling the domain. Expose this reset line in the V3D
binding.

Keep the property optional, as devices like the Broadcom Cygnus don't have
a reset line.
