crypto: hisilicon/zip - adds the max shaper type rate 

mainline inclusion
from mainline-master
commit 38a9eb81
category: feature
bugzilla: 173981
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=38a9eb8182a24c7ef2dbe82ab46cafe8f8e9b271



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

The ZIP driver support configure each function's QoS in the Host
for Kunpeng930. The ZIP driver needs to configure the maximum shaper
