atheros: v3.18: relocate PCI host DMA base definition
Put AR2315_PCI_HOST_SDRAM_BASEADDR macro to DMA header, since this is arbitrary value and not some hw specific constant. Also this relocation decouples dma from HW specific header. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com> SVN-Revision: 44716
