Since usb5744 i2c initialization routine uses i2c SMBus APIs these APIs should only be invoked when kernel has I2C support. This new kernel config describes the dependency on I2C kernel support and fix the below build issues when USB_ONBOARD_DEV=y and CONFIG_I2C=m. riscv64-linux-ld: drivers/usb/misc/onboard_usb_dev.o: undefined reference to `i2c_find_device_by_fwnode' drivers/usb/misc/onboard_usb_dev.c:408:(.text+0xb24): undefined reference to `i2c_smbus_write_block_data' Parsing of the i2c-bus bus handle is not put under usb5744 kernel config check as the intention is to report an error when DT is configured for usb5744 SMBus support and kernel has USB_ONBOARD_DEV_USB5744 disabled.
