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
- Do not embed comma in the macro, so to treat that just as another
item and please source code formatting tools
