src/include: Move storage class to beginning of declaration

Fix the following warning detected by checkpatch.pl:

WARNING: storage class should be at the beginning of the declaration

The following storage class attribute is not detected by checkpatch.py:

	static cbmem_init_hook_t init_fn_ ## _ptr_ __attribute__((used,
\
	section(".rodata.cbmem_init_hooks"))) = init_fn_;

The following lines generates a false positive:

(pound)define STATIC static
src/include/cpu/amd/common/cbtypes.h:60: WARNING: storage class should
be at the beginning of the declaration

typedef asmlinkage void (*smm_handler_t)(void *);
src/include/cpu/x86/smm.h:514: WARNING: storage class should be at the
beginning of the declaration

(pound)define MAYBE_STATIC static
src/include/stddef.h:34: WARNING: storage class should be at the
beginning of the declaration

TEST=Build and run on Galileo Gen2
