ASoC: intel: skylake: Set max DMA segment size

Browse source 
The recent code refactoring to use the standard DMA helper requires
the max DMA segment size setup for SG list management.  Without it,
the kernel may spew warnings when a large buffer is allocated.

This patch sets up dma_set_max_seg_size() for avoiding spurious
warnings.

Fixes: 2c95b92ecd ("ALSA: memalloc: Unify x86 SG-buffer handling (take#3)")
