Update the PFVF logic to handle restart and recovery. This adds the
following functions:
* adf_pf2vf_notify_fatal_error(): allows the PF to notify VFs that the
device detected a fatal error and requires a reset. This sends to
VF the event `ADF_PF2VF_MSGTYPE_FATAL_ERROR`.
* adf_pf2vf_wait_for_restarting_complete(): allows the PF to wait for
`ADF_VF2PF_MSGTYPE_RESTARTING_COMPLETE` events from active VFs
before proceeding with a reset.
* adf_pf2vf_notify_restarted(): enables the PF to notify VFs with
an `ADF_PF2VF_MSGTYPE_RESTARTED` event after recovery, indicating that
the device is back to normal. This prompts VF drivers switch back to
use the accelerator for workload processing.
These changes improve the communication and synchronization between PF
and VF drivers during system restart and recovery processes.

With the growing number of Intel crypto drivers, it makes sense to
group them all into a single drivers/crypto/intel/ directory.
