drm/i915/dg1: Compute MEM Bandwidth using MCHBAR
The PUNIT FW is currently returning 0 for all memory bandwidth
parameters. Read the values directly from MCHBAR offsets 0x5918 and
0x4000(4).
v2 (Lucas): tidy up checking for ret slightly
v3 (Lucas):
- Squash change to double the memory bandwidth based on
MCHBAR Gear_type
- Move ICL_GEAR_TYPE_MASK to the appropriate place and change prefix
to DG1
- Move register definitions to i915_reg.h
- Make the MCHBAR path permanent for DG1
- Convert to REG_BIT()/REG_GENMASK()
v4: Drop unneeded initializations
