__initconst should only be used for const data, but this array isn't
const. Only the strings the pointer in this array point to are constant.

So you have to use either

	static const char *axi_parents[] __initdata = {

or

	static const char * const axi_parents[] __initconst = {

.

Best regards
Uwe
