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.
