gpu: nvgpu: prod programming for slcg timer unit

Browse Source 
Added init function for common.ptimer unit and called
this init function during nvgpu early init.
int nvgpu_ptimer_init(struct gk20a *g);

Added following helper function for programming
prod values for slcg timer unit:
void nvgpu_cg_slcg_timer_load_enable(struct gk20a *g);

Invoked prod programming for slcg timer unit from
nvgpu_ptimer_init.
