Intel: dmaengine: ioatdma: Add Snow Ridge ioatdma device id

mainline inclusion
from mainline-v5.1-rc1
commit 4d75873f
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I47H3V
CVE: NA

--------------------------------

commit 4d75873f upsream.

Add Snowridge Xeon-D ioatdma PCI device id. Also applies for Icelake
