drm/i915/mtl: Update CHICKEN_TRANS* register addresses
In Display version 14, Transcoder Chicken Registers have updated address.
This patch performs checks to use the right register when required.
v2: Omit display version check in i915_reg.h(Jani)
v3:
- Remove extra whitespace introduced
- Fix reg definitions for MTL_CHICKEN_TRANS(MattR)
Bspec: 34387, 50054
