drm/xe: Use REG_FIELD/REG_BIT for all regs/*.h 

Convert the macro declarations to the equivalent GENMASK and
and bitfield prep for all registers.

v2 (Matt Roper):
  - Fix wrong conversion of RPM_CONFIG0_CRYSTAL_CLOCK_FREQ_MASK
  - Reorder fields of XEHP_SLICE_UNIT_LEVEL_CLKGATE for consistency
  - Simplify CTC_SOURCE_* by only defining CTC_SOURCE_DIVIDE_LOGIC
    as REG_BIT(0)

v3: Also remove DOP_CLOCK_GATE_ENABLE that is unused and wrongly defined
