Reduce the use of i915_reg_defs.h so it can be encapsulated in a single
place.
1) If it was being included by mistake, remove
2) If it was included for FIELD_GET()/FIELD_PREP()/GENMASK() and the
like, just include <linux/bitfield.h>
3) If it was included to be able to define additional registers, move
the registers to the relavant headers (regs/xe_regs.h or
regs/xe_gt_regs.h)
v2:
- Squash commit fixing i915_reg_defs.h include and with the one
introducing regs/xe_reg_defs.h
- Remove more cases of i915_reg_defs.h being used when all it was
needed was linux/bitfield.h (Matt Roper)
- Move some registers to the corresponding regs/*.h file (Matt Roper)
