PATCH 1/1 usb: chipidea: ci_hdrc_imx: Pass DISABLE_DEVICE_STREAMING flag to imx6ul

From: Fabio Estevam <[email protected]>

According to the i.MX6UL Errata document:
https://www.nxp.com/docs/en/errata/IMX6ULCE.pdf

ERR007881 also affects i.MX6UL, so pass the CI_HDRC_DISABLE_DEVICE_STREAMING flag to workaround the issue.
