ARM: tegra: fix pmc_pwrgate_timer_mult register definition
Register pmc_pwrgate_timer_mult has a different layout on Tegra114 and
Tegra124. Reflect this in pmc.h.
Also, simply write the whole of the register in start_cpu() rather than
doing a read-modify-write; the register is simple enough that the code
can easily construct the entire desired value.
