OMAP3+: introduce generic ABB support
Adaptive Body Biasing (ABB) modulates transistor bias voltages
dynamically in order to optimize switching speed versus leakage.
Adaptive Body-Bias ldos are present for some voltage domains
starting with OMAP3630. There are three modes of operation:
* Bypass - the default, it just follows the vdd voltage
* Foward Body-Bias - applies voltage bias to increase transistor
performance at the cost of power. Used to operate safely at high
OPPs.
* Reverse Body-Bias - applies voltage bias to decrease leakage and
save power. Used to save power at lower OPPs.
