hx4700: regulator: declare full constraints
commit a52d209336f8fc7483a8c7f4a8a7d2a8e1692a6c upstream. Since the removal of CONFIG_REGULATOR_DUMMY option, the touchscreen stopped working. This patch enables the "replacement" for REGULATOR_DUMMY and allows the touchscreen to work even though there is no regulator for "vcc".
