gpu: nvgpu: Use sw ops for PMU PG unit

Browse Source 
Some functions are not accessing hardware directly
but are being called using HAL ops: For example

g->ops.pmu.pmu_elpg_statistics,
g->ops.pmu.pmu_pg_init_param,
g->ops.pmu.pmu_pg_supported_engines_list,
g->ops.pmu.pmu_pg_engines_feature_list,
g->ops.pmu.pmu_is_lpwr_feature_supported,
g->ops.pmu.pmu_lpwr_enable_pg,
g->ops.pmu.pmu_lpwr_disable_pg,
g->ops.pmu.pmu_pg_param_post_init,
g->ops.pmu.save_zbc

Change the function access by using sw ops, like:
Create new functions:

int nvgpu_pmu_elpg_statistics(struct gk20a *g, u32 pg_engine_id,
		struct pmu_pg_stats_data *pg_stat_data);
void nvgpu_pmu_save_zbc(struct gk20a *g, u32 entries);
bool nvgpu_pmu_is_lpwr_feature_supported(struct gk20a *g,
			u32 feature_id);
