drm/i915: Remove skl_ddl_allocation struct
Current consensus that it is redundant as
we already have skl_ddb_values struct out there,
also this struct contains only single member
which makes it unnecessary.
v2: As dirty_pipes soon going to be nuked away
from skl_ddb_values, evacuating enabled_slices
to safer in dev_priv.
v3: Changed "enabled_slices" to be "enabled_dbuf_slices_num"
(Matt Roper)
v4: - Wrapped the line getting number of dbuf slices(Matt Roper)
- Removed indeed redundant skl_ddb_values declaration(Matt Roper)
