gpu: nvgpu: use support_ls_pmu flag to check LS PMU support

Browse Source 
Currently PMU support enable check is done with multiple
methods which added complexity to know status of PMU
support.

Changed to replace multiple methods with support_pmu
flag to know the PMU support, support_pmu will be updated
at init stage based on platform/chip specific settings
to know the PMU support status.

Cleaned up support_pmu flag check with platform specific
PMU members in multiple places & moved check to
public functions
