drm/v3d: Deprecate the use of the Performance Counters enum

Browse Source 
The Performance Counters enum used to identify the index of each
performance counter and provide the total number of performance
counters (V3D_PERFCNT_NUM). But, this enum is only valid for V3D 4.2,
not for V3D 7.1.

As we implemented a new flexible structure to retrieve performance
counters information, we can deprecate this enum.

* In order to check for performance counter information,

* Don't use V3D_PERFCNT_NUM to retrieve the maximum number of performance
