[PATCH RFC 02/13] ARM: OMAP2+: hwmod: AMx3: runtime AM335x handling

Update AM335x CLKCTRL, RSTCTRL, RSTST offsets, clockdomain & ocpif clk
that differ with AM43x at runtime. This is being done so that static
initialization of these details (which are different between AM335x
and AM43x) can be removed to aid in sharing of hwmod data between both
platforms as much as possible.
