arm64, topology: enable use of init_cpu_capacity_cppc() 

mainline inclusion
from mainline-v5.17-rc8
commit 82909316
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I7C2TX
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=82909316caac1ef3320b94c57bd0915aac90b0bd



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

Now that the arch topology driver provides a method of setting CPU
capacity values based on information on highest performance from CPPC,
use this functionality on arm64 platforms.
