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.

Revision history:
v3 =>:
- No changes

v2 => v3:
- The ldon-head dt-property was changed to microvolts. Adapt the driver
to that
RFCv1 => v2:
- No changes

There are some new variants planned. Most notably, the BD73900 should be
similar to the BD72720 what comes to the regulator control logic.

If the run-level control is needed, there are some downstream extensions
available at:

+ * The BUCK10 on BD72720 has two modes of operation, depending on a LDON_HEAD

+ *
+ * However, when LDON_HEAD is set to 0x1 ... 0x7, BUCK 10 voltage is, according

+ *
+ * Again, reading the data-sheet shows a "typical connection" where the BUCK10

+ * 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.
