clk: samsung: s3c64xx: declare s3c64xx_clk_init() in shared header 



The s3c64xx_clk_init() is defined and used by the clk-s3c64xx driver and
also used in the mach-s3c64xx machine code.  Move the declaration to a
header to fix W=1 build warning:

    drivers/clk/samsung/clk-s3c64xx.c:391:13: warning: no previous prototype for 's3c64xx_clk_init' [-Wmissing-prototypes]
      391 | void __init s3c64xx_clk_init(struct device_node *np, unsigned long xtal_f,
