  Log:
  Don't enable I/O or memory mode in a device's command register if the BAR
  we are processing has a base address of zero.  Note that this will only
  change behavior for devices where all the BARs of a given type have a base
  address of 0 since we will enable the appropriate access when we encounter
  the first BAR with a base that is not 0.  Specifically, this allows certain
  Toshiba laptops to no longer require 'hw.pci.enable_io_modes=0' to avoid
  hangs during boot.
