The definition
static const char *axxia_dt_match[] __initconst = {
...
defines a changable array of constant strings. That is you must not do:
*axxia_dt_match[0] = 'k';
but
axxia_dt_match[0] = "different string";
is fine. So the annotation __initconst is wrong and yields a compiler
error when other really const variables are added with __initconst.
As the struct machine_desc member dt_compat is declared as
const char *const *dt_compat;
making the arrays const is the better alternative over changing all
annotations to __initdata.
