The BCM2835 PM block has exposed a reset line for the V3D block since
commit 670c672608a1 ("soc: bcm: bcm2835-pm: Add support for power domains
under a new binding."), which allows the GPU to be reset without
power-cycling its domain. Document it so that the vc4 driver can use it to
recover from a GPU hang.Keep the property optional, as existing device trees do not describe it.
