arm: mach-k3: am642: Store boot info from ROM

For AM642, ROM supports loading system firmware directly
from boot image. ROM passes information about the number of
images that are loaded to bootloader at a specific address
that is temporary.  Add support for storing this information
somewhere permanent before it gets corrupted.
