[PATCH] regulator: ab8500: Provide map_voltage() functions

[Mark Brown]

From: Mark Brown <broonie@xxxxxxxxxx>

Since all the voltage tables for ab8500 are sorted in ascending order we
can improve performance by using regulator_map_voltage_ascend(). A couple
of the regulators can actually use linear maps which would be even better.
