[PATCH -next 1/3] clk: sprd: composite: Fix unsigned comparison with less than zero

The return value of the sprd_div_helper_round_rate() is long.
However, the return value is being assigned to an unsigned
long variable 'rate', so making 'rate' to long.

silence the warning:
./drivers/clk/sprd/composite.c:20:5-9: WARNING: Unsigned expression
compared with zero: rate < 0
