The field of page size in register GITS_BASERn might be read-only if an implementation only supports a single, fixed page size. But currently the ITS driver will throw out an error when PAGE_SIZE is less than the minimum size supported by an ITS. So addressing this problem by using 64KB pages as default granule for all the ITS base tables.
