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.
