WED is supported just for mmio devices, so do not check it for usb or
sdio devices. This patch fixes the crash reported below:

A number of users reported that this support was working fine before
it got removed. Add it back, but leave out the unsupported 80+80 mode.

Trying to probe a mt7921e pci card without firmware results in a
successful probe where ieee80211_register_hw hasn't been called. When
removing the driver, ieee802111_unregister_hw is called unconditionally
leading to a kernel NULL pointer dereference.
Fix the issue running mt76_unregister_device routine just for registered
hw.
