[PATCH 06/17] spi: dw: Add DW SPI DMA/PCI/MMIO dependency on DW SPI core

[Serge Semin <Sergey.Semin@xxxxxxxxxxxxxxxxxxxx>]

Seeing all of the DW SPI driver components like DW SPI DMA/PCI/MMIO
depend on the DW SPI core code it's better to use the if-endif
conditional kernel config statement to signify that common dependency.
