ARM: vexpress: Enable regulator framework when MMCI is in use
The MMCI driver, when used with a Device Tree described device, relies on the "vmmc" voltage regulator supply to set the OCR register voltage bits, using MMC core's mmc_regulator_get_supply() function. Without the regulator framework present there are no valid operating voltages reported and the device initialisation fails: mmci-pl18x 10005000.mmci: No vmmc regulator found mmci-pl18x 10005000.mmci: no support for card's volts mmc0: error -22 whilst initialising SD card Signed-off-by: Pawel Moll <pawel.moll@arm.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
