[ARM] nommu: Provide a simple flush_dcache_page implementation
nommu doesn't require a complex flush_dcache_page implementation like the MMU-ful CPUs do, so provide a simplified version in nommu.c and omit flush.c from the build as appropriate. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
