[PATCH 03/10] imx943_evk: Enable USB 2.0 controller host mode

[Alice Guo (OSS)]

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

This patch enables the USB 2.0 controller to operate in host mode on the
i.MX943 EVK board. It updates the device tree files to configure the USB
2.0 controller appropriately and modifies the defconfig to include
necessary support.
