Changes for v1: - Refactor USB PHY register definitions to a common header file to enable code sharing between ehci-mx6.c and ci_udc.c. - Fix the usb_oc_config() function to correctly handle overcurrent configuration on i.MX7/8M/9/7ULP/8/8ULP platforms, where the register layout differs from i.MX6. - Extract PHY initialization code into a reusable function that can be shared between ehci-mx6.c and ci_udc.c. - Convert the ci_udc driver to use driver model. - Updating Kconfig to automatically select DM_USB_GADGET when CI_UDC is enabled. - Add i.MX8ULP platform support.
Tested on i.MX8ULP EVK board with USB mass storage functionality.
