[PATCH 1/2] drm/xe/guc: Allow to initialize submission with limited set of IDs

[Michal Wajdeczko <michal.wajdeczko@intel.com>]

While PF and native drivers may initialize submission code to use
all available GuC contexts IDs, the VF driver may only use limited
number of IDs. Update init function to accept number of context
IDs available for use.
