[PATCH v2] CLKDEV: return from clk_find as soon as we get maching clk

[Viresh KUMAR]

clk_find function looks for clock with matching dev_id and con_id.
We should return from clk_find as soon as we get a clock with matching dev_id
and con_id. This can be done by comparing variable "match" with 3.

v2:
	- remove if (match == 0), check.
	- move match==3 in if (match > best) condition
