mmc: tmio: add support for the VccQ regulator Some SD/MMC interfaces use 2 power regulators: one to power the card itself (Vcc) and another one to pull signal lines up (VccQ). In case of eMMC and UHS SD cards the regulators also have to be configured to supply different voltages. The preferred order of turning supply power on and off is to turn Vcc first on and last off.
