mmc: sdhci-iproc: add SDHCI_QUIRK2_HOST_OFF_CARD_ON for cygnus

BugLink: http://bugs.launchpad.net/bugs/1786352
commit 3de06d5a1f05c11c94cbb68af14dbfa7fb81d78b upstream.

The SDHCI_QUIRK2_HOST_OFF_CARD_ON is needed for the driver to
properly reset the host controller (reset all) on initialization
after exiting deep sleep.
