From: Marcel Ziswiler <marcel.ziswiler@toradex.com>
Add mmc-ddr-1_8v property enabling eMMC DDR52 mode.
root@colibri-t30:~# cat /sys/kernel/debug/mmc1/ios
clock: 52000000 Hz
actual clock: 52000000 Hz
vdd: 21 (3.3 ~ 3.4 V)
bus mode: 2 (push-pull)
chip select: 0 (don't care)
power mode: 2 (on)
bus width: 3 (8 bits)
timing spec: 8 (mmc DDR52)
signal voltage: 1 (1.80 V)
driver type: 0 (driver type B)
root@colibri-t30:~# hdparm -t /dev/mmcblk1
/dev/mmcblk1:
Timing buffered disk reads: 222 MB in 3.00 seconds = 73.92 MB/sec
