LF-3064 Revert "arm64: dts: imx8mq-evk: Add MIPI DSI support"

This reverts commit d367e7d.

As designed, the default dtb imx8mq-evk can only support one
display: DCSS + native HDMI, and dtb imx8mq-evk-dual-display
is dedicated for multiple dislay.

And current multiple displays is implemented by two different
DRM devices with two DRI cards generated. But Weston UI cannot
make sure to choose DCSS for UI display device, so revert this
patch to solve this kind of problem.
