OMAP3: control/PM: move padconf save code to mach-omap2/control.c
Move the padconf save code from pm34xx.c to the System Control Module
code in mach-omap2/control.c. This is part of the general push to
move direct register access from middle-layer core code to low-level
core code, so the middle-layer code can be abstracted to work on
multiple platforms and cleaned up.
In the medium-to-long term, this code should be called by the mux
layer code, not the PM idle code. This is because, according to the
TRM, saving the padconf only needs to be done when the padconf
changes[1].
