usb: mtu3: move vbus and mode debugfs interfaces into mtu3_debugfs.c
Due to the separated debugfs files are added, move vbus and mode debugfs interfaces related with dual-role switch from mtu3_dr.c into mtu3_debugfs.c Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>hifive-unleashed-5.2
