w1: mxc: fix build

Now that header files no longer include common.h it must be included
first.

Otherwise the build fails with errors like
	include/asm/arch/clock.h:43:1: error: unknown type name 'u32'
	 u32 imx_get_uartclk(void);

Fixes: c3dc39a2f85b ("arm: Don't include common.h in header files")
