Subject[PATCH v5 0/4]implement eMMC4.4 standard HW reset feature
Hi,
This is the version 5 of HW reset feature implementation. HW reset can
reset eMMC card when card occurs a read/write/erase timeout error. It is
useful when eMMC card cannot correspond any command after occurs a timeout
error.

change-log:
patch1: use value 5 instead to judge whether eMMC card complies eMMC4.41
standard.
patch4: handle erase timeout error only when there was an error occurs
after erase.

patch1: enable HW reset capability if card support.

patch2: add two new callback to implement HW reset in mmc core layer. In
this patch, routine mmc_handle_timeout_error was added.

patch3: implement hardware_reset callback for sdhci host. A new callback
reset_emmc was defined which will be each sdhci host controller to
implement separately.

patch4: did a HW reset after each read/write/erase command if need.

Thanks
Chuanxiao
