Subject: [PATCH] pci: remove unused HAVE_ARCH_PCI_SET_DMA_MAX_SEGMENT_{SIZE|BOUNDARY}

In 2.6.34, we transformed the PCI DMA API into the generic device
mode. The PCI DMA API is just the wrapper of the DMA API.

So we don't need HAVE_ARCH_PCI_SET_DMA_MAX_SEGMENT_SIZE or
HAVE_ARCH_PCI_SET_DMA_SEGMENT_BOUNDARY (which enable architectures to
have the own implementations). Both haven't been used anyway.

Applied to my linux-next branch, thanks.
