[PATCH] vfio/qat: add support for intel QAT 6xxx virtual functions

[Suman Kumar Chakraborty]

From: Małgorzata Mielnik <malgorzata.mielnik@intel.com>

Extend the qat_vfio_pci variant driver to support QAT 6xxx Virtual
Functions (VFs). Add the relevant QAT 6xxx VF device IDs to the driver's
probe table, enabling proper detection and initialization of these devices.

Update the module description to reflect that the driver now supports all
QAT generations.
