Previously the driver would revert to internal supply if the external supply couldn't be found. This had multiple problems: - it caused silently ignored errors when a regulator was intended to be supplied, but was not specified correctly. - if CONFIG_REGULATOR is disabled, regulator_get() will always return a dummy regulator, which caused a device to always use the external vref mode, even though there is none. This patch addresses the issue by adding a platform data structure, containing a boolean field use_external_ref. If the platform data structure is present and if that boolean is set, the external vref is used; otherwise the internal vref is used. In the case where an external vref is wanted but regulator_get() fails, the driver no longer reverts to using the internal vref, but returns an error instead.
