[PATCH] fix ARCH_IXP4XX compile error

[FUJITA Tomonori]

The commit 4fa5518c65df7a2c4b6c58061ac53d0b01228042 breaks
CONFIG_ARCH_IXP4XX:

linux-2.6/arch/arm/mach-ixp4xx/common-pci.c:340: error: redefinition of 'dma_needs_bounce'
linux-2.6/arch/arm/include/asm/dma-mapping.h:294: note: previous definition of 'dma_needs_bounce' was here
make[2]: *** [arch/arm/mach-ixp4xx/common-pci.o] Error 1

This is a safe option. Can we remove dma_needs_bounce in common-pci.c
too?
