ALSA: memalloc: Convert x86 SG-buffer handling with non-contiguous type
We've had an x86-specific SG-buffer handling code, but now it can be merged gracefully with the standard non-contiguous DMA pages. After the migration, SNDRV_DMA_TYPE_DMA_SG becomes identical with SNDRV_DMA_TYPE_NONCONTIG on x86, while others still fall back to SNDRV_DMA_TYPE_DEV. The remaining problem is about the SG-buffer with WC pages: the DMA core stuff on x86 doesn't treat it well, so we still need some special handling to manipulate the page attribute manually. The mmap handler for SNDRV_DMA_TYPE_DEV_SG_WC still returns -ENOENT intentionally for the fallback to the default handler.
