clk: samsung: Define a common samsung_clk_register_pll()
This patch defines a common samsung_clk_register_pll() Since pll2550 & pll35xx and pll2650 & pll36xx have exactly same clk ops implementation, added pll2550 and pll2650 also. Signed-off-by: Yadwinder Singh Brar <yadi.brar@samsung.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>
