ARM: fix clps711x, footbridge, integrator, ixp2000, ixp2300 and s3c build bug
Anders Grafström reports that footbridge fails to build after 1c4a4f4. Fix this by adding the necessary definitions for __pfn_to_bus and __bus_to_pfn. Reported-by: Anders Grafström <anders.grafstrom@netinsight.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
