Subject: mmc: sdio: Fix invalid vdd in voltage switch power cycle

From: Adrian Hunter <[email protected]>

commit d9bfbb95ed598a09cf336adb0f190ee0ff802f0d upstream.

The 'ocr' parameter passed to mmc_set_signal_voltage() defines the power-on voltage used when power cycling after a failure to set the voltage. However, in the case of mmc_sdio_init_card(), the value passed has the R4_18V_PRESENT flag set which is not valid for power-on and results in an invalid vdd. Fix by passing the card's ocr value which does not have the flag.
