    if_dwc: fix reinitialization with changed MAC

    It was observed that on RockPro64 hardware, the dwc interface is unable
    to receive packets after being assigned a new MAC address. The fix is
    simply to call mii_mediachg() before touching any device registers in
    dwc_init_locked(). This is consistent with what the OpenBSD driver does.
