ARM: tegra: power: Use CONFIG_PM_SLEEP instead of CONFIG_PM

For Linux 2.6.39, CONFIG_PM_SLEEP is the proper kernel configuration
parameter to use on Tegra for power management, and not CONFIG_PM.
CONFIG_PM does not have the required dependency on CONFIG_SUSPEND
necessary to pull in the CPU suspend/resume functionality used by
Tegra.

Also fixes compilation errors when CONFIG_PM and by implication
CONFIG_PM_SLEEP are not configured.
