tegra: hwpm: update and add IOCTLs in UAPI header

Browse Source 
- Add resource_info IOCTL to return status of HWPM resources.
- Remove TEGRA_SOC_HWPM_RESOURCE_MSS_NVLINK which is duplicate of
MSS_GPU_HUB.
- Add logic for resource_info IOCTL in the driver code.
- Ptimer and TSC timer have 1:1 relation. Hence timer relation IOCTLs
are not required.
