[PATCH 1/3] clk: imx: Declare clock init functions in header acessible from mach

[Krzysztof Kozlowski]

Multiple files from arch/arm/mach-imx/ use clock init functions which
are defined in the IMX clock drivers.  Declare them in globally
accessible header to fix GCC warnings:

  drivers/clk/imx/clk-imx21.c:122:74: warning: no previous prototype for 'mx21_clocks_init' [-Wmissing-prototypes]
