crypto: qat - add support for 402xx devices

QAT_402xx is a derivative of 4xxx. Add support for that device in the
qat_4xxx driver by including the DIDs (both PF and VF), extending the
probe and the firmware loader.

402xx uses different firmware images than 4xxx. To allow that the logic
that selects the firmware images was modified.
