usb: mtu3: fix failed runtime suspend in host only mode

Browse Source 
[ Upstream commit 1c703e29da ]

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()
