[U-Boot] [PATCH v4 07/18] ls102xa: esdhc: Add esdhc support for LS102xA

[Alison Wang]

For LS102xA, the platform is little endian, while esdhc IP is
big endian. So two macros are added, CONFIG_SYS_FSL_ESDHC_LE
and CONFIG_SYS_FSL_ESDHC_BE, to determine the registers'
reading/writing in big or little endian format.
