CHROMIUM: ASoC: Intel: Skylake: Use SG allocation for SKL-based firmware load
Resign from ->alloc_dma_buf() and use snd_dma_alloc_pages() directly.
For data i.e.: base firmware binary transfer, make use of SG allocation
to better adapt to memory-limited environment. For BDL descriptor, given
its small size this is not required.
BUG=b:171808591, b:239715995, b:235443521
TEST=eve with memory restricted via 'mem=4G' command line parameter.
Run youtube either via the browser or via ARCVM, and run suspend/resume
cycles. Without this patch it consistently fails on the first or second
resume. With this patch I haven't been able to get a failure.
