ARM: tegra: clock: Reduce Tegra3 pll post-lock delay

Reduced pll post-lock delay from 50us to 2us.

Rearranged wait for lock loop to delay first check of lock bit
by 2us after pll is enabled.

Added read fence for PLLM lock via PMC (in this case enable bit is
in APB bus register, but lock detect bit is in PPSB bus register).

Bug 1017271
