    ARM: dts: qcom: ipq8064: reduce pci IO size to 64K
    
    [ Upstream commit 8fafb7e5c041814876266259e5e439f93571dcef ]
    
    The current value for pci IO is problematic for ath10k wifi card
    commonly connected to ipq8064 SoC.
    The current value is probably a typo and is actually uncommon to find
    1MB IO space even on a x86 arch. Also with recent changes to the pci
    driver, pci1 and pci2 now fails to function as any connected device
    fails any reg read/write. Reduce this to 64K as it should be more than
    enough and 3 * 64K of total IO space doesn't exceed the IO_SPACE_LIMIT
    hardcoded for the ARM arch.
