drivers: mmc: omap_hsmmc: Fix IO Buffer on OMAP36xx
On the OMAP36xx/37xx the CONTROL_WKUP_CTRL register has a field (bit 6) named GPIO_IO_PWRDNZ. If 0, the IO buffers which are related to GPIO_126, 127 and 129 are disabled. Some boards may need this for MMC. After the PBIAS is configured, this bit should be set high to enable these GPIO pins.
