ARM: S5PC1XX: Change clksrc_clks to use array of clocks
Remove the individual 'struct clksrc_clks' and place them into an array so that we can simply use s3c_register_clksrcs to register tham all in one go. Since the spdif clock relies on the audio clock, move the audio clocks into their own arrary. Thanks to Marek Szyprowski for testing and pointing out the four clocks what where missed from the clock list. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
