5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xu Yang <xu.yang_2@xxxxxxx>
[ Upstream commit 9a070e8e208995a9d638b538ed7abf28bd6ea6f0 ]
Use dedicated imx8ulp usb compatible to remove QoS request
since imx8ulp has no such limitation of imx7ulp: DMA will
not work if system enters idle.
