mmc: core: add eMMC hardware reset support
eMMC's may have a hardware reset line. This patch provides a
host controller operation to implement hardware reset and
a function to reset and reinitialize the card. Also, for MMC,
the reset is always performed before initialization.
The host must set the new host capability MMC_CAP_HW_RESET
to enable hardware reset.
