ls102xa: esdhc: Add esdhc support for LS102xA
For LS1, esdhc is big-endian IP. Accessing the registers should be in big-endian mode. So we use esdhc_read32() to read Host controller capabilities register for LS1. For LS1, when using CMD12, cmdtype need to be set to ABORT, otherwise, next read command will hang. Signed-off-by: Alison Wang <alison.wang@freescale.com>
