agp/ati: Use PCI_COMMAND instead of hard-coded 4
We're accessing the PCI_COMMAND register here, so use the appropriate #define. The bit we're writing (1 << 14) isn't defined by the PCI or PCIe spec, so we don't have a name for it. No functional change. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
