[v2,0/7] crypto: hisilicon - fix some issues in hisilicon drivers

This patchset fixes some issues of the HiSilicon accelerator drivers.

The first patch uses 128bit atomic operations to access mailbox instead of
the generic IO interface. The reason is that one QM hardware entity in
one accelerator servers QM mailbox MMIO interfaces in related PF and VFs.
A mutex cannot lock mailbox processes in different functions.

The second patch allocs memory for mailbox openration when the driver is
bound to the device. The software directly returns after waiting for the
mailbox times out, but the hardware does not cancel the operation. If the
temporary memory is used, the hardware may access the memory after it is
released.

The third patch enables the maximum number of queues supported by the
device instead of returning error, when the maximum number of queues is
less than the default value.

The fourth patch checks the number of queues on the function before
algorithm registering to crypto subsystem. If the number of queues
does not meet the minimum number of queues for task execution, the
function is not registered to crypto to avoid process initialization
failure.

The fifth patch adds a cond_resched() to prevent soft lockup.
The sixth patch fixes aeq type value. 
The last patch increases function communication waiting time so that the
PF can communicate with all VFs.

v2:
 - Re-describe the issues resolved by these patches.
 - Fix some code styles.
