usb: gadget: udc: renesas_usb3: add debugfs to set the b-device mode
This patch adds debugfs to set the "b-device" mode for using a board
which is not connected to the ID pin (e.g. CN11 on Salvator-X).
If we want to use peripheral mode on such a board, we have to disable
VBUS output first. So, this patch can set such a mode as the following:
# mount -t debugfs none /sys/kernel/debug
# modprobe renesas_usb3
# modprobe g_mass_storage file=/dev/shm/test.bin
# echo 1 > /sys/kernel/debug/ee020000.usb/b_device
