rpi3: fix RPI3_PRELOADED_DTB_BASE usage
In case if `RPI3_PRELOADED_DTB_BASE` isn't defined explicitly with
proper pre-loaded DTB address, `add_define` macro defined in
`make_helpers/build_macros.mk` still supplies this definition to the
compiler like `-DRPI3_PRELOADED_DTB_BASE`, and it's obviously is set to
default value 1.
This simply leads to the wrong `MAP_NS_DTB` region definition (base_va
is set `0x1` instead of `0x00010000`) in `plat/rpi3/rpi3_common.c`:
Which causes aligment check to fail in `mmap_add_region_check()`:
VERBOSE: base_pa: 0x00000001, base_va: 0x00000001, size: 0x00010000
...
ERROR: mmap_add_region_check() failed. error -22
