dt-bindings: mfd: Common ROHM PMIC properties

ROHM PMICs keep having similar functionalities from one generation to the
next. Keeping the device-trees describing these functionalities similar
helps users because:
  1. They can re-use existing device-tree properties when switching from
     one project, using a ROHM PMIC, to next project using newer
     variant.
  2. The users can find and re-use examples from old projects - even if
     they never worked with ROHM PMICs before.
Similarly, introducing new and different properties for same
functionality previous variant had, will be adding confusion.

Sometimes the existing properties aren't 100% what reviewers would
prefer. When issues are minor or just cosmetic, changing the existing
properties is not feasible. Reviewers can't be expected to know which
properties are new, and which are existing - and this can lead to
unnecessary review discussion wasting time and energy from everyone.

Adding a common file for re-used ROHM PMIC properties should make it
clearly visible that a property is re-used, when a new PMIC binding
refers to this file instead of (re-)describing all the existing
bindings. This will also help keeping the common properties identical
across the variants.

Add new file listing commonly used ROHM PMIC properties.
