[PATCH] clk: sunxi-ng: fix ccu_mmc_timing.c kernel-doc issues

[Randy Dunlap <rdunlap@infradead.org>]

Use '-' to separate the function name and its description.
Use '%' on constants in kernel-doc notation.
Use the kernel-doc Return: format for function return values.

Fixes this warning:
ccu_mmc_timing.c:21: warning: No description found for return value of 'sunxi_ccu_set_mmc_timing_mode'
