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.
