39913acedd Move eSDHC adapter card identification to board files
The eSDHC adapter card identification and multiplexing configuration
through FPGA had been implemented in both common mmc driver and
fsl_esdhc driver. However it is proper to move these code to board
files and do it during board initialization. The FPGA registers are
also board specific.

This patch is to move eSDHC adapter card identification and
multiplexing configuration from mmc driver to specific board files.
And the option CONFIG_FSL_ESDHC_ADAPTER_IDENT is no longer needed.

f34ccce50a mmc: fsl_esdhc: drop CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT
CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT is not the correct method
to set I/O to 1.8. To boards that does not support vqmmc-supply,
use vs18_enable in fsl_esdhc_cfg. If regulator is supported,
use fixed 1.8V regulator for vqmmc-supply.

5a8dbdc6b4 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.

ee0c538951 mmc: fsl_esdhc: Add support to force VSELECT set
Some boards cannot do voltage negotiation but need to set the VSELECT
bit forcely to ensure it to work at 1.8V.

This commit adds CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT flag for this use.

c82e9de400 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.
