mmc: cqhci: add emmc hardware reset after cqe recovery

Browse Source 
When an eMMC error occurs due to changes in hardware conditions
(such as temperature, voltage, etc.), it may not return to normal
without reinitializing the eMMC. In this case, adding hardware
reset and reinitialization can solve the problem.
