[PATCH] ARM: imx: fix imx51 babbage SD2 CD/WP

[Shawn Guo]

Pads GPIO1_6 and GPIO1_5 are used as SD2 CD/WP on imx51 babbage board.
Before commit 5d23b39 (ARM: i.MX51 iomux: add missed definitions for
SION-bit and mode for some pads) gets in, we use the pad settings
configured by bootloader with NO_PAD_CTRL and SD2 CD/WP just works.
The commit changes the pad settings and causes SD2 CD/WP stop working.

Set up pads GPIO1_6 and GPIO1_5 in the configuation that bootloader
uses on imx51 babbage board to fix the SD2 CD/WP regression.
