spi: topcliff-pch: don't hardcode PCI slot to get DMA device
The DMA is a function 0 of the multifunction device where SPI host is attached. Thus, we may avoid to hardcode PCI slot number. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Mark Brown <broonie@linaro.org>
