Rather than treating multicast registers as 'i915_reg_t' let's define them as a completely new type. This will allow the compiler to help us make sure we're using multicast-aware functions to operate on multicast registers.
This plan does break down a bit in places where we're just maintaining heterogeneous lists of registers (e.g., various MMIO whitelists used by perf, GVT, etc.) rather than performing reads/writes. We only really care about the offset in those cases, so for now we can "cast" the registers as non-MCR, leaving us with a list of i915_reg_t's, but we may want to look for better ways to store mixed collections of i915_reg_t and i915_mcr_reg_t in the future.
