    mvebu: mochabin: enlarge PCI memory window
    
    Armada 7040 uses a rather small 15MB memory window for every PCI adapter,
    however this is not sufficient for Qualcomm QCA6390 802.11ax cards that
    are shipped along with the OpenWrt WLAN model of MOCHAbin as ath11k
    requires at least 16MB of memory.
    
    So, similar to what MACCHIATOBin has been doing for years, lets move
    to using the second PCIe 2 memory window and expand it to 128MB to
    make it future proof.
    
    This has been already sent upstream [1].
