[PATCH 4/7] mmc: sdhci-of-k1: Improve power control

[Yixun Lan]

From: Long Wan <long.wan@xxxxxxxxxxxxxxxxxx>

The default sdhci_set_power() skips the SD bus voltage select field
entirely when a vmmc regulator is present, leaving SD Bus Power in off
state of the power control register. To fix this, configure the bus
voltage explicitly.
