Subject: [PATCH 07/10] mmc: sdhci: am654: Use quirk instead of custom set_power()

With the introduction of SDHCI_QUIRK2_SET_BUS_VOLTAGE there is no need
to use a custom set_power() implementation as the quirk takes care of
configuring the bus voltage register even when powering trough a
regulator.
