ENGR00315894-75 iMX6SX:SABRESD Support the reworked eMMC on SD4
The eMMC chip on iMX6SX SABRESD board is DNP at default. HW rework is
needed to weld it on the eMMC socket and disconnect SD card slot.
The pins IOMUX of eMMC are different with SD card slot:
1. The eMMC uses 8 data pins, while SD card slot only uses 4 bits.
2. The CD pin used by SD card slot works as a data pin for eMMC.
So adding a new u-boot target "mx6sxsabresd_emmc" for the eMMC support,
rather than using the SD boot configuration.
