The introduction of the media GT brings a few changes for GuC/HuC. The
main difference between the 2 GTs is that only the media one has the
HuC, while both have the GuC. Also, the fact that both GTs use the same
G-unit and GGTT means we now have parallel interrupt/communication
paths. Lastly, WOPCM is divided between the two GTs, with each having
their own private chunk.
v2: address review comments.
v3: comment improvements, minor clean-up.
