crypto: qat - add bank state save and restore for qat_420xx

Register the functions required to save and restore the state of a ring
bank on the qat_420xx device. Since this logic is shared across QAT
GEN4 devices, reuse the existing GEN4 implementation.

This functionality enables saving and restoring the state of a Virtual
Function (VF), which is required for supporting VM Live Migration.
