usb: mtu3: allow system suspend during active gadget connection

Browse source

When operating in gadget mode connected to a USB host, system suspend
fails with -EBUSY because active peripheral connections block suspend
entry.

Fix this by restricting the -EBUSY check to runtime autosuspend
(PMSG_IS_AUTO). For system suspend (!PMSG_IS_AUTO), perform soft
disconnect to disconnect from the bus and allow MAC sleep.
