[PATCH v3 4/8] drm/amd/pm: Add navi1x throttler translation

Some ASICs use a single VR_MEM bit, whereas others split it into VR_MEM0 and VR_MEM1. To avoid confusion, we've combined the VR_MEM0 and VR_MEM1 bits on those ASICs. For consistency we did the same with LIQUID0 and LIQUID1.

[Quan, Evan] I'm wondering why you map the two ASIC dependent bits to the same non ASIC independent bit. Instead of defining two non ASIC independent bits.

[Quan, Evan] Same question here and for Patch4.
