[PATCH 2/3] drm/i915/skl: Rework MOCS tables to keep common part in a define

[Lucas De Marchi]

From: Tomasz Lis <tomasz.lis at intel.com>

The MOCS tables are going to be very similar across platforms.

To reduce the amount of copied code, this patch rips the common part and
puts it into a definition valid for all gen9 platforms.

v2: Made defines for or-ing flags. Renamed macros from MOCS_TABLE
    to MOCS_ENTRIES. (Joonas)
v3 (Lucas):
  - Fix indentation
  - Rebase on rework done by additional patch
  - Remove define for or-ing flags as it made the table more complex by
    requiring zeroed values to be passed
