[PATCH v1 7/7] imx8ulp_evk: Enable USB controller at 0x29920000 in device mode

[alice.guo at oss.nxp.com]

From: Alice Guo <alice.guo at nxp.com>

Update the i.MX8ULP EVK device tree files and defconfig to enable the
second USB controller (base address 0x29920000) on i.MX8ULP EVK in
device mode, allowing the board to operate as a USB mass storage gadget.
