97a7b9928a mmc: sh_mmcif: enable MMC_MODE_HC
The controller can control high capacity cards. So, the patch adds
the flag. If the flag is not set, "mmcinfo" will fail when a high
capacity card is used.

48972d907a mmc: Implement card detection.
Check for card detect each time an MMC/SD device is initialized. If card
detection is not implemented, this code behaves as before and continues
assuming a card is present. If no card is detected, has_init is reset
for the MMC/SD device (to force initialization next time) and an error
is returned.
