regulator: twl-regulator: make TWL4030_ALLOW_UNSUPPORTED more configurable.
The regulators in the twl4030 can provide some voltage settings
that are not offically supported.
These settings are disabled by default, but can be enabled with
CONFIG_TWL4030_ALLOW_UNSUPPORTED=y
However
- that config variable is not mentioned in any Kconfig so cannot
be used, and
- a global setting is clumsy - a per regulator setting would be
better.
So define a new 'feature' flag that a board file can set to enable
these unsupported volatages for boards which need them.
This flag cannot (yet) be set using device-tree.
