[PATCH V2 15/17] i2c: nomadik: Convert to late and early system PM callbacks

[Ulf Hansson]

At system suspend_late, runtime PM has been disabled by the PM core
which means we can safely operate on these resources. Consequentially
we no longer have to wait until the noirq phase of the system suspend.
