Add the mt76::chip class on top of the USB transport: 32-bit register read/write via vendor requests, register polling, and EFUSE reads with the kick/control sequence from transport/mt76.c. Expose chip_id() and mac_address() (with the 62:45:bd fallback). Verified on hardware: chip ID 0x7612 (MT7612) and MAC address read from EFUSE. Co-Authored-By: qwen3.8-27b@q2_k_xl: ported register and EFUSE layer
