regulator: improved mode error checks
Minor bugfixes in handling of regulator modes:
- have the routine verifying regulator modes check against
the set of legal modes (!);
- have regulator_set_optimum_mode() verify the return value
of regulator_ops.get_optimum_mode(), like drms_uA_update();
- one call to regulator_ops.set_mode() treated zero as a
failure code; make this consistent with other callers.
Both regulator_set_mode() and regulator_set_optimum_mode() now
require valid_ops_mask to include REGULATOR_CHANGE_MODE; that
seems like a bugfix too.
