The Blend/ROP Sub Unit (BRS) is a stripped-down version of the BRU found in several VSP2 instances. Compared to a regular BRU, it supports two inputs only, and thus has no ROP unit. Add support for the BRS by modelling it as a new entity type, but reuse the vsp1_bru object underneath. Chaining the BRU and BRS entities seems to be supported by the hardware but isn't implemented yet as it isn't the primary use case for the BRS.
