usb: gadget: f_ecm: Add suspend/resume and remote wakeup support

Browse source

When host sends suspend notification to the device, handle
the suspend callbacks in the function driver. Depending on
the remote wakeup capability the device can either trigger a
remote wakeup or wait for the host initiated resume to resume
data transfer.
