Matti Vaittinen f16a9d76a7 regulator: bd71828: Support ROHM BD72720 
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.

* The BUCK10 on BD72720 has two modes of operation, depending on a LDON_HEAD
* setting. When LDON_HEAD is 0x0, the behaviour is as with other bucks, eg.
* voltage can be set to a values indicated below using the VSEL register.
*
* However, when LDON_HEAD is set to 0x1 ... 0x7, BUCK 10 voltage is, according
* to the data-sheet, "automatically adjusted following LDON_HEAD setting and
* clamped to BUCK10_VID setting".
*
* Again, reading the data-sheet shows a "typical connection" where the BUCK10
* is used to supply the LDOs 1-4. My assumption is that in practice, this
* means that the BUCK10 voltage will be adjusted based on the maximum output
* of the LDO 1-4 (to minimize power loss). This makes sense.
*
* Auto-adjusting regulators aren't something I really like to model in the
* driver though - and, if the auto-adjustment works as intended, then there
* should really be no need to software to care about the buck10 voltages.
* If enable/disable control is still needed, we can implement buck10 as a
* regulator with only the enable/disable ops - and device-tree can be used
* to model the supply-relations. I believe this could allow the regulator
* framework to automagically disable the BUCK10 if all LDOs that are being
* supplied by it are disabled.
