clk: imx: clk-cpu: Include "clk.h" header file

From: Fabio Estevam <[email protected]>

Include the "clk.h" header file to fix the following sparse warning:

drivers/clk/imx/clk-cpu.c:77:12: warning: symbol 'imx_clk_cpu' was not declared. Should it be static?

Changes since v1:
- Rebased since the clk-cpu moved to drivers/clk/imx
