refactor(imx8mp): cleanup the mmap region settings

Introduce the bl_regions array to gather all regions and make use of the
MAP_REGION_FLAT() macro. The array is than passed to mmap_add() to map
all regions. While on it introduce some defines so the addr, size and
flags can be read more easily. No functional change done.
