[PATCH v1 24/24] board: colibri-imx6ull: fix detecting sd card

[sbabic at denx.de]

> From: Marcel Ziswiler <marcel.ziswiler at toradex.com>
> Turns out on certain carrier boards (e.g. Iris V2) and under certain
> circumstances (e.g. after a software reset) the SD card may have been
> left in a strange state which later failed as follows:
> Colibri iMX6ULL # mmc dev 0
> Card did not respond to voltage select! : -110
> Fix this as follows:
> - Re-name the signaling voltage rail regulator from vmmc to vqmmc.
> - Fix the name of the GPIO property to gpios.
> - Specify 4-bit bus width, no write-protect capability and no 1.8
>   volt signaling voltage capability.
> - Fix the clock vs. command pull-up vs. push-pull configuration.
