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



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.
