There is no fsl,imx8mq-dwc3 binding doc, no driver use this compatible
string. Drop it.

please don't. I'm not aware of the driver state but the compatibles are
there for _possible_ quirk handling, so the driver can add a match on
demand.

NXP downstream also not has driver use this compatible string, and pass
several GA releases.
People could add it back when it is needed together with binding doc.

This shouldn't be an argument, because there is no bug at the moment
doesn't mean that there is one. Also the compatible may used by other
projects using this device tree too.
> People could add it back when it is needed together with binding doc.
Nope since a DTB is firmware which is updated relativ rare. The kernel
instead is updated more often. So please instead of removing it add
support to the dt-bindings doc.
