Serge Semin acf994151d dmaengine: dw-edma: Depend on DW_EDMA instead of selecting it 
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.
