There is no need to use *_noirq version of suspend and resume PM callbacks. The
suspend_late / resume_early suit better (it was discussed in [1]) and in future
could be used for runtime PM support.

This code sequence:
if (!pdev->dev.dma_mask) {
pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask;
pdev->dev.coherent_dma_mask = DMA_BIT_MASK(32);
}
bypasses the architectures check on the DMA mask. It can be replaced
with dma_coerce_mask_and_coherent(), avoiding the direct initialization
of this mask.

In rare cases (mostly for the testing purposes) the dw_dmac driver might be
compiled as a module as well as the other LPSS device drivers (I2C, SPI,
HSUART). When udev handles the event of the devices appearing the dw_dmac
module is missing. This patch will fix that.

To simplify the driver development let's split driver to library and platform
code parts. It helps us to add PCI driver in future.
