arm: dts: colibri-imx7: clean-up sd card dts

Keep +3.3V pull-ups interface by default in SOM DTSI imx7-colibri.dtsi

SD card interface setting per board device tree:
imx7-colibri-aster.dtsi       +3.3V pull-ups
imx7-colibri-eval-3.dtsi      +3.3V pull-ups
imx7-colibri-iris.dtsi	      +3.3V pull-ups
imx7-colibri-iris-v2.dtsi     1.8V signaling, no pull-ups, UHS capable
