[PATCH 04/18] rockchip: add weak function symbol called at the beginning of misc_init_r

Most Rockchip boards who override misc_init_r do it only to call another
function and keep the rest unchanged. Therefore to allow for less
duplication, let's just add a weak function symbol that is called inside
misc_init_r.
