From: Jerry Huang <chang-ming.hu...@freescale.com>
For the current u-boot codes, only 4bit/1bit SD/SDHC bus width is support.
So for MMC card, we also support 4bit bus width,
otherwiase, we will get the 12bit bus width, which is not correct:
=> mmcinfo
Device: FSL_SDHC
Manufacturer ID: 1e
OEM: ffff
Name: MMC
Tran Speed: 52000000
Rd Block Len: 512
MMC version 4.0
High Capacity: No
Capacity: 1.9 GiB
Bus Width: 12-bit
