Kconfig "select" is discouraged for visible symbols like DW_EDMA because it makes it possible to set DW_EDMA even if DW_EDMA depends on things that are not set (see Documentation/kbuild/kconfig-language.txt). Convert DW_EDMA_PCIE so it depends on DW_EDMA instead of selecting it. There will likely be several future drivers that depend on DW_EDMA, so this uses "if DW_EDMA" to enclose them all rather than repeating "depends on DW_EDMA" for each.
