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.
