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
