Please add U postfix to these constants to address compiler warning
as reported by kbuild-all@xxxxxx:

>> drivers/clk/samsung/clk-exynos7.c:43:2: warning: this decimal constant is
unsigned only in ISO C90
PLL_35XX_RATE(2496000000, 208, 2, 0),

You can remove this panic() call, there is already one inside
samsung_clk_init().
