ARM: tegra: rethink the cpu suspend-resume code path
The current kernel methodology expects that tegra_cpu_suspend
is actually the last function in the entire suspend sequence.
In order to achieve this, the code needs to be remodelled a
bit so that we actually execute native cpu_suspend at the end
of the suspend sequence. This allows us to leverage all the
cpu_suspend code developed by ARM in the upstream kernels.
