ARM: tegra: amend pmc.h for Tegra114+
Tegra114 and later's PMC module removes the pwrgate_timer_on register and replaces it with a clamp_status register. Adjust pmc.h to reflect this, and update any code affected by the change. The cpu.c change in this patch was extracted from a much larger patch by Jimmy Zhang. The pmc.h change was written from scratch, but inspired by related changes made by Tom Warren. There could well be other differences in the PMC register set for chips after Tegra20/30. However, they don't affect the code in U-Boot at present, so I haven't attempted an exhaustive update of pmc.h.
