Subject: [PATCH v3 0/2] Add support for querying hw info that UMDs need

From: John Harrison <John.C.Harrison at Intel.com>

Various UMDs require hardware configuration information about the current platform. A bunch of static information is available in a fixed table that can be retrieved from the GuC.

v2: Rebased to newer baseline and added a kerneldoc comment.
v3: Rebased to newer baseline and newer GuC interface.
