[PATCH] ASoC: kirkwood: cleanup the external clock probe

[Jean-Francois Moine]

This patch checks the return value of the clk_prepare_enable of the
external clock and removes the test about a same internal and external
clock which would quite never occur and won't work in most cases
it would occur.
