    pci: fix PCI resource reserve capability on BE
    
    PCI resource reserve capability should use LE format as all other PCI
    things. If we don't then seabios won't boot:
    
    === PCI new allocation pass #1 ===
    PCI: check devices
    PCI: QEMU resource reserve cap: size 10000000000000 type io
    PCI: secondary bus 1 size 10000000000000 type io
    PCI: secondary bus 1 size 00200000 type mem
    PCI: secondary bus 1 size 00200000 type prefmem
    === PCI new allocation pass #2 ===
    PCI: out of I/O address space
    
    This became more important since we started reserving IO by default,
    previously no one noticed.
