[PATCH v2 0/4] Introduce GuC context ID Manager

[Michal Wajdeczko]

While we are already managing GuC IDs directly in GuC submission
code, using bitmap() for MLRC and ida() for SLRC, this code can't
be easily extended to meet additional requirements for SR-IOV use
cases, like limited number of IDs available on VFs, or ID range
reservation for provisioning VFs by the PF.
