Subject: [PATCH -v2 15/16] PCI: x86: use generic pcibios_set_master()

From: Myron Stowe <mstowe@...hat.com>

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.
