Are the above configs meant to enable a specific skus of BYT with designware I2S? 
For BYT-I, the ASoC is not upstream yet.

drivers/i2c/busses/i2c-designware-pcidrv.c does not contain BYT support yet,
so is this intentional to make it "m" now?

drivers/spi/spi-pxa2xx-pci.c does not contain BYT support yet,
so is this intentional to make it "m" now?

Should "DW_DMAC_PCI" be added since it has been added into LTSI patches.baytrail/1139-dma-dw-add-PCI-part-of-the-driver.patch

Suggest to move these configs to be next to CONFIG_PINMUX.

The PWM for BYT driver has not been up-streamed yet.
