PATCH 1/1 ARM: dts: qcom: ipq8064: disable mmc-ddr-1_8v for sdcc1
It was reported non working mmc with this option enabled. Both mmc for ipq8064 are supplied by a fixed 3.3v regulator so mmc can't be run at 1.8v.
Disable it to restore correct functionality of this SoC feature.

Perhaps there's some board where this property makes sense, but it seems like something that should be added when needed in the leaf DTS, and not supplied in the base DTSI. So:
This also fixes problems I've seen on my systems, so:
Thanks!
