Vedashree Vidwans c220f9f46f tegra: hwpm: return error from read/write function ...

Currently, read/write functions validate aperture and mmio address
pointers. However, the error cannot be returned to the parent resulting
into undetected errors.
Modify all read write functions to return error on failure. This will
also allow HWPM driver to know about unavailable IP perfmuxes.
