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.
