soc: hisilicon: kunpeng_hccs: Add failure log for no _CRS method 

mainline inclusion
from mainline-v6.8-rc1
commit e1e720f3f2c50a6f3440b3684decd7b7c046e111
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8Y3PY
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.6-rc1&id=e1e720f3f2c50a6f3440b3684decd7b7c046e111



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

Driver gets the PCC channel id by using the PCC GAS in _CRS.
But, currently, if the firmware has no _CRS method on platform, there
is not any failure log. So this patch adds the log for this.
