wifi: mt76: mt792x: add common USB transport reset helpers

Browse Source 
Add per-device USB reset work and a control-path access check helper
for mt7921u and mt7925u.

This prepares common infrastructure for transport-level recovery while
keeping the reset state per-device for correct lifetime handling.

No functional change intended.
