Jani Nikula baa09e7d2f drm/i915: use REG_FIELD_PREP() to define register bitfield values 
Slightly verbose, but does away with hand rolled shifts. Ties the field
values with the mask defining the field.

Unfortunately we have to make a local copy of FIELD_PREP() to evaluate
to a integer constant expression. But with this, we can ensure the mask
is non-zero, power of 2, fits u32, and the value fits the mask (when the
value is a constant expression).

Convert power sequencer registers as an example.

v4:
- rebase

v3:
- rename the macro to REG_FIELD_PREP to avoid underscore prefix and to
  be in line with kernel macros (Chris)
- rename power of 2 check macro (Chris)

v2:
 - add build-time checks with BUILD_BUG_ON_ZERO()
 - rename to just _FIELD() due to regmap.h REG_FIELD() clash
