regulator: qpnp-regulator: add support for FTS 2.5 type regulators 



Add support for QPNP PMIC FTS 2.5 type regulators.  This type of
regulator supports auto mode control, auto phase control, and
three phases enabled at one time.  The FTS 2.5 voltage mapping is
similar to that of existing FTS 2 except for an additional
offset.
