[PATCH v9 03/14] dmaengine: idxd: Rename drv_enable/disable_wq to idxd_drv_enable/disable_wq, and export

[Tom Zanussi]

Rename drv_enable_wq and drv_disable_wq to idxd_drv_enable_wq and
idxd_drv_disable_wq respectively, so that they're no longer too
generic to be exported.  This also matches existing naming within the
idxd driver.

And to allow idxd sub-drivers to enable and disable wqs, export them.
