PCI: Support BAR sizes up to 8TB

Browse source

Current kernel reports that BARs larger than 128GB, e.g., this 4TB BAR, are
disabled:

    pci 0000:01:00.0: disabling BAR 4: [mem 0x00000000-0x3ffffffffff 64bit pref] (bad alignment 0x40000000000)

Increase the maximum BAR size from 128GB to 8TB for future expansion.
