X-Git-Tag: firefly_0821_release~9833^2~2609^2~3^2~87

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.
