Subject: [PATCH] dmaengine: ioatdma: Add Snow Ridge ioatdma device id
Git-commit: 4d75873f814055359bb6722c4e35a185d02157a8
Patch-mainline: v5.1-rc1
References: jsc#SLE-5442
Add Snowridge Xeon-D ioatdma PCI device id. Also applies for Icelake
SP Xeon. This introduces ioatdma v3.4 platform. Also bumping driver version
to 5.0 since we are adding additional code for 3.4 support.
