According to the imx8mq data sheet running VDD_GPU at 0.9V is enough
when not overclocking to 1GHz (which we currently don't do).

changes from v2:
 - rebase aginst Shawn's tree
 - fix a warning for the typec connector

Rename usb_typec to usb-typec to get a rid of a warning when building
dtb with warnings enabled.

This one should also be prefixed like arm64: dts: imx8mq-librem5-devkit:

I fixed it up and applied both.
