msm: krait-regulator: add regulator control for kraits

Badger kraits have a single voltage supply coming from the pmic. This
supply is provided by multiple switching regulators operating in
ganged mode.

There is a LDO and a HS (Head Switch) per core that further control the
voltage supply to that core.

This driver manages the ganged supply by calling upon the spm driver to
set phases and voltage.
