Subject: [PATCH v2 16/23] arm64: dts: colibri-imx8x: Add no-1-8-v to sd-card

From: Philippe Schenker <philippe.schenker@...adex.com>

Many Colibri carrier boards are using 3.3V pull-up resistors on the
SD-Card connector. Letting it switch to 1.8V is an invalid state.

Do prevent this from happening by keeping the signaling voltage at 3.3V.
