ia64: fix build failure with CONFIG_SWIOTLB

arch/ia64/kernel/pci-swiotlb.c is removed in commit 4fac8076df85 ("ia64: clean up swiotlb support")
but pci-swiotlb.o is still present in Makefile, and so build fail when
CONFIG_SWIOTLB is enabled.
Fix the build failure by removing pci-swiotlb.o from makefile
