dmaengine: idxd: Add Max SGL Size Support for DSA3.0
Certain DSA 3.0 opcodes, such as Gather copy and Gather reduce, require max
SGL configured for workqueues prior to supporting these opcodes.
Configure the maximum scatter-gather list (SGL) size for workqueues during
setup on the supported HW. Application can then properly handle the SGL
size without explicitly setting it.
