tmio_mmc: Use 100ms mmc_detect_change() delay
This patch changes the tmio_mmc driver to wait 100ms before checking the card detect status. This type of delay is quite common among mmc drivers, it seems that most hardware platforms need to give the hardware some time to settle before checking card availabilty. Hotplug is half-broken without this patch on the sh7724 Ecovec board. Hot insertion seems ok but eject is never detected without this patch.
