apalis/colibri_t30: mmc: sdhci: hack to make newer cards work
SDR12, SDR25, SDR50, SDR104 and DDR50 all require 1.8V signalling which
our current T30 designs can't do. Newer cards will fail as follows:
Kingston 32GB microSDHC class 10
[ 69.000280] mmc1: error -84 whilst initialising SD card
SanDisk Mobile Ultra 8GB microSDHC I
[ 28.289174] mmc1: error -110 whilst initialising SD card
This patch activates a quirk which signals our lack of 1.8V support.
