[Intel-gfx] [PATCH v3 0/1] Add sysfs interface to control class-of-service

[Prathap Kumar Valsan]

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.
