crypto: hisilicon/qm - support new function communication
On the HiSilicon accelerators drivers, the PF/VFs driver can send messages
to the VFs/PF by writing hardware registers, and the VFs/PF driver receives
messages from the PF/VFs by reading hardware registers. To support this
feature, a new version id is added, different communication mechanism are
used based on different version id.
