Drivers need to handle !PM case with work arounds for managing clocks
and power explicitly, which is not really necessary when PM support on
tegra is in good shape. In fact ARM 64-bit tegra platforms enforce PM
support and there is no reason why this cannot be done for 32-bit.

This patch selects PM unconditionally and drivers can rely on runtime
PM framework for clock and power management.
