ata: dwc: add DMADEVICES dependency
The dwc_460ex SATA driver has become available on non-powerpc architectures
and may cause randconfig build errors when CONFIG_DMADEVICES is not set
and SATA_DWC_OLD_DMA is enabled:
warning: (SATA_DWC_OLD_DMA) selects DW_DMAC_CORE which has unmet direct dependencies (DMADEVICES)
ERROR: "dw_dma_probe" [drivers/ata/sata_dwc_460ex.ko] undefined!
ERROR: "dw_dma_remove" [drivers/ata/sata_dwc_460ex.ko] undefined!
This adds an explcit Kconfig dependency to CONFIG_SATA_DWC so we
cannot run into broken configurations. While it would also be
possible to build the driver with both CONFIG_DMADEVICES
and SATA_DWC_OLD_DMA disabled, that case is not useful because
there is no fallback to PIO mode when the DMA engine is not
usable.
