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.
