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.
