cpufreq: s3c24xx: Fix broken s3c_cpufreq_init()
commit a307a1e6bc0d "cpufreq: s3c: use cpufreq_generic_init()" accidentally broke cpufreq on s3c2410 and s3c2412. These two platforms don't have a CPU frequency table and used to skip calling cpufreq_table_validate_and_show() for them. But with the above commit, we started calling it unconditionally and that will eventually fail as the frequency table pointer is NULL. Fix this by calling cpufreq_table_validate_and_show() conditionally again.
