LoongArch inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IB1H2M
--------------------------------
The policy->cur was not being initialized properly during CPU initialization, leading to it always reporting 0. This commit addresses this issue by setting the initial frequency to the normal maximum frequency.
This ensures that the current frequency reflects the actual CPU operating frequency.
