The operating mode of the Adaptive Body-Bias ldo is a function of the
voltage at which the VDD is operating and silicon characteristics.
NOMINAL_OPP causes the ABB ldo to be in bypass at that specific voltage.
FAST_OPP causes the ldo to operate in Forward Body-Bias mode. SLOW_OPP
puts the ldo in Reverse Body-Bias mode.
This patch models this relationship by adding an opp_sel paramter to
struct omap_volt_data and populates this data in the 3630 and 4430
voltage tables.
Not all voltage domains have an ABB ldo and 3430 doesn't have one at
all. In such cases voltages are marked with OMAP_ABB_NO_LDO.
