vfio/qat: extend Kconfig dependencies for 420xx and 6xxx devices

Currently, the QAT VFIO PCI driver can only be configured when the 4xxx
QAT driver (CRYPTO_DEV_QAT_4XXX) is enabled. This is too restrictive as
the VFIO driver also supports VFs from the 420xx and 6xxx device
families, which share a compatible migration interface.

Extends the Kconfig dependencies to allow configuration when any of the
supported QAT device families (4xxx, 420xx, or 6xxx) are enabled.
