[PATCH] clk: provide clk_is_match() dummy for non-common clk

[arnd@arndb.de (Arnd Bergmann)]

ARM randconfig build tests found a new error for configurations
with COMMON_CLK disabled but HAS_CLK selected by the platform:

ERROR: "clk_is_match" [sound/soc/fsl/snd-soc-fsl-spdif.ko] undefined!

This moves the declaration around, so this case is covered
by the existing static inline helper function.

Fixes: c69e182e51d89 ("clk: introduce clk_is_match")
----
BTW, we have a preexisting problem in clk_get_parent,
clk_round_rate and clk_set_parent, which I've worked around in
my randconfig builds so far. Should we do that the same way?
