    lantiq: fix patching the wifi mac address on BTHOMEHUBV3A
    
    The firmware hotplug script tries to read the mac address from a
    partition with the name "uboot-env" which does not exist (instead it's
    name is uboot_env). This broke calculation of the new checksum (after
    patching the mac address) which resulted in ath9k refusing to use the
    EEPROM data.
    
    The original error reported by ath9k was:
    PCI: Enabling device 0000:00:0e.0 (0000 -> 0002)
    ath: phy0: Bad EEPROM checksum 0x2523
    ath: phy0: Unable to initialize hardware; initialization status: -22
    ath9k 0000:00:0e.0: Failed to initialize device
    
    Fixes: a20616863d32d9 ("lantiq: use ath9k device tree bindings
    binding/owl-loader")
