    drm/xe/pmu: Add GT frequency events
    
    Define PMU events for GT frequency (actual and requested). This is
    a port from the i915 driver implementation, where an internal timer
    is used to aggregate GT frequencies over certain fixed interval.
    Following PMU events are being added-
    
      xe_0000_00_02.0/gt-actual-frequency/              [Kernel PMU event]
      xe_0000_00_02.0/gt-requested-frequency/           [Kernel PMU event]
    
    Standard perf commands can be used to monitor GT frequency-
      $ perf stat -e xe_0000_00_02.0/gt-requested-frequency,gt=0/ -I1000
    
         1.001175175                700 M    xe/gt-requested-frequency,gt=0/
         2.005891881                703 M    xe/gt-requested-frequency,gt=0/
         3.007318169                700 M    xe/gt-requested-frequency,gt=0/
    
    Actual frequencies will be reported as 0 when GT is in C6.
    
    v2: Use locks while storing/reading samples, keep track of multiple
    clients (Lucas) and other general cleanup.
