dmaengine: idxd: add wq driver name support for accel-config user tool
[ Upstream commit 7af1e0aceeb321cbc90fcf6fa0bec8870290377f ]
With the possibility of multiple wq drivers that can be bound to the wq,
the user config tool accel-config needs a way to know which wq driver to
bind to the wq. Introduce per wq driver_name sysfs attribute where the user
can indicate the driver to be bound to the wq. This allows accel-config to
just bind to the driver using wq->driver_name.
