PCI: x86: use generic pcibios_set_master()
This patch removes x86's architecture-specific 'pcibios_set_master()' routine and lets the default PCI core based implementation handle PCI device 'latency timer' setup. No functional change. Signed-off-by: Myron Stowe <myron.stowe@redhat.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
