gpu: nvgpu: use HAL for chiplet offset

We currently use hard coded values of NV_PERF_PMMGPC_CHIPLET_OFFSET and
NV_PMM_FBP_STRIDE which are incorrect for Volta

Add new GR HAL get_pmm_per_chiplet_offset() to get correct value per-chip
Set gr_gm20b_get_pmm_per_chiplet_offset() for older chips
Set gr_gv11b_get_pmm_per_chiplet_offset() for Volta

Use HAL instead of hard coded values wherever required
