Kunpeng930 could be able to stop queue by writing hardware registers,
which will trigger tasks in device to be flushed out.

In order to be compatible with the kunpeng920 driver, add 'qm_hw_ops_v3' to
adapt Kunpeng930. And 'stop_qp' callback is added in 'qm_hw_ops_v3' to
write hardware registers. Call 'stop_qp' to drain the tasks in device
before releasing queue.

----------------------------------------------------------------------

Kunpeng930 supports queue doorbell isolation.
When doorbell isolation is enabled, it supports to obtain the
maximum number of queues of one function from hardware register.
Otherwise, the 'max_qp_num' is the total number of queues.

When assigning queues to VF, it is necessary to ensure that the number
of VF queues does not exceed 'max_qp_num'.

'qm_init_qp_status' is just a help function to initiate some 'QP' status.
'QP' status should be updated separately.
This patch removes the updating flags in 'QP' status.

When the devices are removed or not existing, the corresponding algorithms
which are registered by 'hisi-zip' driver can't be used.

Move 'hisi_zip_register_to_crypto' from 'hisi_zip_init' to
'hisi_zip_probe'. The algorithms will be registered to crypto only when
there is device bind on the driver. And when the devices are removed,
the algorithms will be unregistered.

In the previous process, the function 'xxx_register_to_crypto' need a lock
and a static variable to judge if the registration is the first time.
Move this action into the function 'hisi_qm_alg_register'. Each device
will call 'hisi_qm_alg_register' to add itself to qm list in probe process
and registering algs when the qm list is empty.

Since the drivers such as HPRE/SEC/ZIP do not implement
'pci_driver.shutdow', a RAS will be triggered at OS rebooting or shutting
down as the hardware device is processing request.
The log looks like this:
	NOTICE:  [NimbusSecNodeType1]:[2372L]This is sec, Base = 0x141800000
	NOTICE:  [NimbusSecHandle]:[2319L] SecIntSt = 0x3

	NOTICE:  [PrintSecurityType]:[344L] SecurityType is RECOVERABLE!

This patch offers a new API in qm to shutdown devices, and add shutdown
callbacks in ACC driver based on this new API.

So the running devices will be stopped when the OS reboot or shutdown.
