    RFC drm/xe/guc: Handle runtime suspend issues for engine busyness
    
    1) During runtime suspend, when card enters D3hot, values read
        from the shared memory maintained by GuC returns 0xFF.
        Waking up for every perf read when
        device is runtime suspended causes power penality.
        Store the last read busy ticks and total active ticks and return
        these values when suspended
    
     2) When the device is runtime resumed, guc is loaded again. If pmu
        interface was opened to collect busyness events, the guc stats
        have to be re-enabled to resume collection after suspend.
        Disable/enable guc stats if pmu is opened and is already collecting
        busyness events and device gets runtime suspended/resumed.
