[U-Boot] [PATCH 2/4] apalis/colibri_t30: fix MMC/SD card detect GPIOs

[Marcel Ziswiler]

This fixes the MMC/SD card detect GPIOs for Apalis T30 which got broken
by the following commit:

2b2b50bc8748bf1ddb2d96da7157f9eecbe24961

While at it also re-add the comments describing which particular
Apalis/Colibri pins those GPIOs are on.
