Adrian Hunter 6c43290972 mmc: sdhci-pci: Fix initialization of some SD cards for Intel BYT-based controllers
commit 2970134b927834e9249659a70aac48e62dff804a upstream.

Bus power may control card power, but the full reset done by SDHCI at
initialization still may not reset the power, whereas a direct write to
SDHCI_POWER_CONTROL can. That might be needed to initialize correctly, if
the card was left powered on previously.
