[Intel-gfx] [CI 1/2] 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)
