cpufreq: loongson3-acpi: Initialize scaling_cur_freq correctly 

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.
