Subject: [PATCH -v2 07/16] PCI: TILE: convert pcibios_set_master() to a
	non-inlined function

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

This patch converts TILE's architecture-specific 'pcibios_set_master()'
routine to a non-inlined function.  This will allow follow on patches
to create a generic 'pcibios_set_master()' function using the '__weak'
attribute which can be used by all architectures as a default which,
if necessary, can then be over-ridden by architecture-specific code.

Converting 'pci_bios_set_master()' to a non-inlined function will
allow TILE's 'pcibios_set_master()' implementation to remain
architecture-specific after the generic version is introduced and
thus, not change current behavior.

No functional change.
