hisi_qm_get_free_qp_num() is to get the free queue number on the function.
It is a simple function and is only called by
hisi_qm_get_available_instances().
This patch modifies to get the free queue directly in
hisi_qm_get_available_instances(), and remove hisi_qm_get_free_qp_num().

hisi_qm_free_qps() can release multiple queues in one call, and it is
already exported. So, replace hisi_qm_release_qp() with hisi_qm_free_qps()
in zip_crypto.c, and do not export hisi_qm_release_qp() outside qm.c.

These functions 'hisi_qm_create_qp' and 'hisi_qm_set_vft' are not
used outside qm.c, so they are marked as static.

The 'hisi_qm_get_hw_version' function is unused, so remove the function

Add last word dumping function during acc engines controller reset.
The last words are reported to the printed information during the
reset. The dmesg information included qm debugging registers and
engine debugging registers. It can help to improve debugging
capability.

We use VF QM state register to record the status of the QM configuration
state. This will be used in the ACC migration driver to determine whether
we can safely save and restore the QM data.

struct pci_driver pointer is an input into the pci_iov_get_pf_drvdata().
Introduce helpers to retrieve the ACC PF dev struct pci_driver pointers
as we use this in ACC vfio migration driver.

Move Doorbell and Mailbox definitions to common header file.
Also export QM mailbox functions.
This will be useful when we introduce VFIO PCI HiSilicon ACC live
migration driver.

Since we are going to introduce VFIO PCI HiSilicon ACC driver for live
migration in subsequent patches, move the ACC QM header file to a
common include dir.
