[PATCH v3 08/23] drm/xe/log: Add SIGID log helpers for components

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

Our component list already defines relation between the component
name, identified by the TAG, and its numerical identifier and the
assigned SIGID. We can also already prepare location identifier
based on the pointer type used to emit the log entry. Add helper
that will prepare SIGID, COMPONENT and LOCATION parameters for
xe_log_emit() using provided components TAG and the pointer.
