Axel Lin ec4f5423b5 ARM: S3C2443: Remove redundant s3c_register_clocks call for init_clocks
Since commit af337f3e63
"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.

Heiko Stuebner 33ccedfd1b ARM: S3C24XX: use clk_get_rate to init fclk in common_setup_clocks
Previously the fclk rate was calculated by dividing the pll through
the divider value of the armdiv. With a real armdiv clk in place it's
possible to simply read its value, which does essentially the same.

This change makes the whole fdiv_fn function pointers supplied to
s3c2443_common_init_clocks and s3c2443_common_setup_clocks
obsolete, so remove it too.

The system-layout of the armdiv and armclk is common to
S3C2443/S3C2416/S3C2450 and only differs in the array of
possible dividers. Therefore it is possible to reuse the
clock definitions for all of these SoCs.
