Tegra: PM: soc-specific system off handler

This patch introduces a power down handler which can be overriden
by SoCs to customise the power down process. The current SoCs do
not have a way of powering down the entire system as external PMIC
chips are involved in the process.

But future SoCs will have a way to power off the entire system
without talking to an external PMIC.
