crypto: hisilicon/qm - increase the maximum waiting timeout interval of the moilbox. 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8LFYK


CVE: NA

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

In the case of high concurrency of multiple threads, the bus is easily
congested when accelerator tasks are running, which prolongs the time
required for mailbox operations. Increase the maximum time for
the driver to wait for the mailbox operation to complete.
