For GEN11 MOCS are part of context register state. This means updating
CLOS also needs to update the context state of active contexts.
v3: Rebase
v2: Updated the interface to use two sysfs files(Joonas)
- Gen12 PCode interface is not ready yet to read the way mask.
So removed TGL support and added support for Gen11.
- Updating MOCS in Gen 11 also require changing the context image of
existing contexts.
Referred to gen8_configure_all_contexts() as suggested by Chris.
