crypto: hisilicon - check _PS0 and _PR0 method

mainline inclusion
from mainline-master
commit 3e1d2c52
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I475PF?from=project-issue
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git/commit/?id=3e1d2c52b2045ba7f90966b02daeb6c438432570

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

To support runtime PM, use the function 'pci_set_power_state' to change
the power state. Therefore, method _PS0 or _PR0 needs to be filled by
platform. So check whether the method is supported, if not, print a
prompt information.
