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.
