crypto: hisilicon/qm - simplify the status of qm

The 'QM_INIT' and 'QM_CLOSE' status of qm and 'QP_INIT'
and 'QP_CLOSE' status of queue are not actually used. Currently,
driver only needs to switch status when the device or queue
is enabled or stopped, Therefore, remove unneeded status to
simplify driver. In addition, rename'QM_START to'QM_WORK' for
ease to understand.

crypto: hisilicon/qm - alloc buffer to set and get xqc

If the temporarily applied memory is used to set or get the xqc
information, the driver releases the memory immediately after the
hardware mailbox operation time exceeds the driver waiting time.
However, the hardware does not cancel the operation, so the hardware
may write data to released memory.

Therefore, when the driver is bound to a device, the driver reserves
memory for the xqc configuration. The subsequent xqc configuration
uses the reserved memory to prevent hardware from accessing the
released memory.

crypto: hisilicon/qm - fix PF queue parameter issue

If the queue isolation feature is enabled, the number of queues
supported by the device changes. When PF is enabled using the
current default number of queues, the default number of queues may
be greater than the number supported by the device. As a result,
the PF fails to be bound to the driver.

After modification, if queue isolation feature is enabled, when
the default queue parameter is greater than the number supported
by the device, the number of enabled queues will be changed to
the number supported by the device, so that the PF and driver
can be properly bound.

crypto: hisilicon/qm - split a debugfs.c from qm

Considering that the qm feature and debugfs feature are independent.
The code related to debugfs is getting larger and larger. It should be
separate as a debugfs file. So move some debugfs code to new file from
qm file. The qm code logic is not modified. And maintainability is
enhanced.
