Subject: [PATCH -v2 01/16] PCI: add declaration for pcibios_set_master() to
	pci core

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

Currently, pcibios_set_master() is implemented in architecture-
specific code.  There is nothing architecture-specific about PCI's
'latency timer'.

This patch adds a declaration for pcibios_set_master() to PCI's core
in preperation for pulling the function itself up into the core.
Without the addition of this declaration, subsequent patches that
remove inline definitions of pcibios_set_master() would be removing
the only declaration of such.

No functional change.
