On the vc4 devices (and later), the blending is done by a single device called the HVS. The HVS has three FIFO that can operate in parallel, and route their output to 6 CRTCs and 7 encoders on the BCM2711.

Each of these CRTCs and encoders have some contraints on which FIFO they can feed from, so we need some code to take all those constraints into account and assign FIFOs to CRTCs.
