mmc: cqhci: Increase recovery halt timeout
commit b578d5d18e929aa7c007a98cce32657145dde219 upstream. Failing to halt complicates the recovery. Additionally, unless the card or controller are stuck, which is expected to be very rare, then the halt should succeed, so it is better to wait. Set a large timeout.
