[RFC 7/8] clk: use strncmp for matching con_id in clk_find

[Tero Kristo <t-kristo@ti.com>]

As clkdev register forces the con_id length down to a maximum of 15
characters and terminating null, replace the internal implementation
of clk_find to use strncmp instead of strcmp. This makes sure that
if a user registers a clkdev with con_id name which gets trimmed,
the same string used in the clk_lookup will still succeed despite
this.
