[PATCH] clk: renesas: rcar-gen2: Change multipliers and dividers to u8

[PATCH] clk: renesas: rcar-gen2: Change multipliers and dividers to u8

[Geert Uytterhoeven]

All multipliers and dividers are small.
Storing them in u8 instead of unsigned int reduces kernel size for a
generic kernel by ca. 0.5 KiB.
