For GEN11 MOCS are part of context register state. This means updating CLOS also needs to update the context state of active contexts. v4: - Make it explicit in the commit message that we want to set CLOS global on device (Chris) - Fixe the Locking (Chris) - Move the global configuration of contexts away from gt.(Chris) v3: Rebase v2: - Update 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.
