Subject: [PATCH v4 11/16] spi: dw: Remove DW DMA code dependency from DW_DMAC_PCI

Since there is a generic method available to initialize the DW SPI DMA
interface on any DT and ACPI-based platforms, which in general can be
designed with not only DW DMAC but with any DMA engine on board, we can
freely remove the CONFIG_DW_DMAC_PCI config from dependency list of
CONFIG_SPI_DW_DMA. Especially seeing that we don't use anything DW DMAC
specific in the new driver.
