From: Małgorzata Mielnik <malgorzata.mielnik@xxxxxxxxx>
The current implementation of the QAT live migration enablers is exclusive
to QAT GEN4 devices and resides within QAT GEN4 specific files. However,
the underlying mechanisms, such as the relevant CSRs and offsets,
can be shared between QAT GEN4 and QAT GEN6 devices.
Add the necessary enablers required to implement live migration for QAT
GEN6 devices to the abstraction layer to allow leveraging the existing
QAT GEN4 implementation.
