IB: Fix RDMA_RXE and INFINIBAND_RDMAVT dependencies for DMA_VIRT_OPS
DMA_VIRT_OPS requires that dma_addr_t is at least as wide as a pointer, which is expressed as a dependency on !64BIT || ARCH_DMA_ADDR_T_64BIT. For parisc64 this is not true, and if these IB modules are enabled, kconfig warns: WARNING: unmet direct dependencies detected for DMA_VIRT_OPS Depends on [n]: HAS_DMA [=y] && (!64BIT [=y] || ARCH_DMA_ADDR_T_64BIT) Selected by [m]: - INFINIBAND_RDMAVT [=m] && INFINIBAND [=m] && 64BIT [=y] && PCI [=y] - RDMA_RXE [=m] && INET [=y] && PCI [=y] && INFINIBAND [=m] Add dependencies to fix this.
