[ Upstream commit 9735bde36487da43d3c3fc910df49639f72decbf ]
On DSA/IAX 1.0, TC-A and TC-B in GRPCFG are set as 1 to have best
performance and cannot be changed through sysfs knobs unless override
option is given.
The same values should be set on DSA 2.0 as well.

Fixes: ade8a86b512c ("dmaengine: idxd: Set defaults for GRPCFG traffic class")
