Introduced two new voltage domain specific parameter structures,
omap_vp_param and omap_vc_param. These are used to describe the minimum
and maximum voltages for the voltagedomains, and also the sleep voltage
levels. Existing voltage levels are also moved into these new structures,
and the voltage domain code is changed to use these.
