Tegra210: save TZSRAM context from the "_wfi" handler

This patch saves the TZSRAM context and takes the SoC into System Suspend
from the "_wfi" handler. This helps us save the entire CPU context from
the TZSRAM, before entering System Suspend. In the previous implementation
we missed saving some part of the state machine context leading to an assert
on System Suspend exit.
