crypto: hisilicon/qm - increase wait time for mailbox

The device requires more time to process queue stop and function stop
mailbox commands compared to other mailbox commands . In the current
driver, the mailbox processing wait time for queue stop and function
stop is less than the device timeout, which may cause the driver to
incorrectly assume that the mailbox processing has failed. Therefore,
the driver wait time for queue stop and function stop should be set to
be greater than the device timeout.  And PF and VF communication
relies on mailbox, the communication wait time should also be modified.
