Starting with OMAP36xx, some voltage domains have an ABB ldo meant to
insure stability when that voltage domain is operating at a high OPP.
This patch adds struct omap_abb_instance to struct voltagedomain and
populates the data for those voltage domains that have an ABB ldo on
both 36xx and 44xx silicon.
