ARM: S3C2443: Remove redundant s3c_register_clocks call for init_clocks

Since commit af337f3e
"ARM: S3C2443: Move parts of the clock code to common clock file",
the init_clocks array is moved to arch/arm/plat-s3c24xx/s3c2443-clock.c.
Now we call s3c_register_clocks for init_clocks in s3c2443_common_init_clocks.

Thus we can remove the empty init_clocks array here and remove the
redundant s3c_register_clocks call for init_clocks in s3c2443_init_clocks.
