Subject: [PATCH AUTOSEL 6.4 11/40] usb: chipidea: imx: don't request QoS for imx8ulp

From: Xu Yang <xu.yang_2@....com>

[ 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.
