MLK-23411 ARM64: dts: imx8mq-evk: disable u1 and u2 entries for typec port
Commit 729dcffd1ed31 ("usb: dwc3: gadget: Add support for disabling
U1 and U2 entries") give detail explaination for user case of
disable u1 and u2 in gadget mode:
"Usecase 1:
When combining dwc3 with an redriver for a USB Type-C device
solution, itsometimes have problems with leaving U1/U2 for
certain hosts, resulting in link training errors and reconnects.
For this U1/U2 state entries may be avoided."
on imx8mq-evk board, we have typec and redriver used and android
reported unstable issue when use some host PC for adb, so to have
a better performance, we disable u1 and u2 entries.
