drm/i915: Introduce parameterized DBUF_CTL
Now start using parameterized DBUF_CTL instead
of hardcoded, this would allow shorter access
functions when reading or storing entire state.
Tried to implement it in a MMIO_PIPE manner, however
DBUF_CTL1 address is higher than DBUF_CTL2, which
implies that we have to now subtract from base
rather than add.
v2: - Removed unneeded DBUF_CTL_DIST and DBUF_CTL_ADDR
macros. Started to use _PICK construct as suggested
by Matt Roper.
v3: - _DBUF_CTL_S* to DBUF_CTL_S*, changed X to "slice"
in macro(Ville Syrjälä)
- Introduced enum for enumerating DBUF slices(Ville Syrjälä)
