ARM: pm: omap3: move saving of the auxiliary control registers to C
Move the saving of the auxiliary control registers into C; there's
no need for this to be in assembly code. This results in less
assembly code to deal with in OMAP.
Kevin tested full-chip retention and off on 3430/n900, 3530/Overo and
3630/Zoom3.
