regulator: bd71828: Support ROHM BD72720

Browse source 
ROHM BD72720 is a power management IC which integrates 10 buck and 11 LDO
regulators. This PMIC has plenty of commonalities with the BD71828 and
BD71879.

The BD72720 does also have similar 'run-level'-concept as the BD71828 had.
It allows controlling the regulator's 'en masse', although only BUCK1
and LDO1 can utilize this in BD72720. Similar to BD71828, this 'en
masse' -control is not supported by this driver.

Support the voltage and enable/disable state control for the BD72720.

This driver supports voltage regulators on ROHM BD71828 PMIC.
This will enable support for the software controllable buck
and LDO regulators.
This driver supports voltage regulators on ROHM BD71828,
BD71879, BD72720 and BD73900 PMICs. This will enable
support for the software controllable buck and LDO regulators.
This driver can also be built as a module. If so, the module
will be called bd71828-regulator.
