Browse code uniphier: support read-only xlat tables BL2 for this platform uses mmap_add_dynamic_region(), but BL31 and BL32 (TSP) only use static mapping. So, BL31 and BL32 can make the tables read-only after enabling MMU. Enable ALLOW_RO_XLAT_TABLES by default.

BL2 for this platform uses mmap_add_dynamic_region(), but BL31 and
BL32 (TSP) only use static mapping. So, BL31 and BL32 can make the
tables read-only after enabling MMU.

Enable ALLOW_RO_XLAT_TABLES by default.
