[ Upstream commit 1c703e29da5efac6180e4c189029fa34b7e48e97 ]
When the dr_mode is "host", after the host enter runtime suspend, the mtu3 can't do it, because the mtu3's device wakeup function is not enabled, instead it's enabled in gadget init function, to fix the issue, init wakeup early in mtu3's probe()
