mmc: fsl_esdhc: Add adapter card type identification support Add adapter card type identification support by reading FPGA STAT_PRES1 register SDHC Card ID[0:2] bits. To use this function, define CONFIG_FSL_ESDHC_ADAPTER_IDENT.

Freescale esdhc-specific options
esdhc: Add CONFIG_SYS_FSL_ESDHC_LE and CONFIG_SYS_FSL_ESDHC_BE macros For LS102xA, the processor is in little-endian mode, while esdhc IP is in big-endian mode. CONFIG_SYS_FSL_ESDHC_LE and CONFIG_SYS_FSL_ESDHC_BE are added. So accessing ESDHC registers can be determined by ESDHC IP's endian mode. Signed-off-by: Alison Wang <alison.wang@freescale.com>

- CONFIG_SYS_FSL_ESDHC_LE
ESDHC IP is in little-endian mode. Accessing ESDHC registers can be
determined by ESDHC IP's endian mode or processor's endian mode.
- CONFIG_SYS_FSL_ESDHC_BE
ESDHC IP is in big-endian mode. Accessing ESDHC registers can be determined
by ESDHC IP's endian mode or processor's endian mode.
