MMC for PXA 27X (resubmit)
MMC support for X_Scale PXA is broken and does not work.
Mainly, the mmc_init() function cannot recognize current SD/MMC cards.
There were already some patches around the world but none of them was
merged into the official u-boot tree.
This patch makes order fixing this issue. Resubmit after code cleanup.
Applied and tested on PXA 270 (TrizepsIV module).
