USB Peripheral (Gadget) mode is always forced to host on boot

[maurosanjo]

Description Using honister I built and image for Raspberry Pi Zero 2 W 64bits adding dwc2 overlay and config ENABLE_DWC2_PERIPHERAL, and when booting dmesg states "Configuration mismatch. dr_mode forced to host"

Steps to reproduce the issue:

1. Build poky-honister for raspberrypi0-2w-64 with dwc2 overlay
2. boot
3. RNDIS does not come up, host mode is forced, unable to up usb0 network interface

Describe the results you received:

g_ether not being loaded was the problem, to solve I had to change some kernel configs:

CONFIG_USB_GADGET=y
CONFIG_USB_ETH=y
CONFIG_USB_ETH_RNDIS=y
CONFIG_INET=y
