Some sdhci hosts may require handling quirks during card initialization
at the time when its type is already known. Hence a new callback
(init_card) is added in sdhci_ops.

I plan to remove init_card and other host ops that sdhci doesn't use (like
sdhci_select_drive_strength).  The driver must provide the mmc op instead.
e.g. in sdhci-xenon.c

	host->mmc_host_ops.init_card = sdhci_xenon_init_card
