drm/amd/display: Set phy_mux_sel bit in dmub scratch register
[Why]
B0 has pipe mux for DIGC and DIGD which can be connected to PHYF/PHYG or
PHYC/PHY D.
[How]
Based on chip internal hardware revision id determine it is B0 and set
DMUB scratch register so DMUBFW can connect the display pipe is
connected correctly to the dig.
