Intel-SIG: commit 63c14ae6 dmaengine: idxd: refactor wq driver enable/disable operations.
Incremental backporting patches for DSA/IAA on Intel Xeon platform.

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

Move the core driver operations from wq driver to the drv_enable_wq() and
drv_disable_wq() functions. The move should reduce the wq driver's
knowledge of the core driver operations and prevent code confusion for
future wq drivers.
