[PATCH 0/4] usb: renesas_usbhs: fixes this driver in gadget mode (part2)

[Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>]

If we tested this driver as gadget, some issues below happened:
 - Oops happened if g_audio.
 - A usb enumeration may fail if we do insmod during connected the usb cable.
 - A transaction will not finish if g_zero.
 - A usb enumeration may fail after we re-connected the usb cable.

This patch serias fixes them.
This patch serias is based on Felipe's usb.git, testing/fixes branch.
