cpufreq: loongson2_cpufreq: adjust cpufreq uses of LOONGSON_CHIPCFG
The post-fork cleanup of loongson2ef from loongson64 changed
LOONGSON_CHIPCFG from a single-argument functional macro to a
non-functional macro with an mmio address in loongson2ef, but
loongson2_cpufreq still uses the notation of a functional macro call
expecting it to be an lvalue. Fixed based on loongson_suspend_enter.
