Add bootscr-address and offset-from-ram-start properties to help in easier
picking of boot script file when automated flows are used.

The bootscr-address holds the full 64 bit address of the bootscript
file.

The bootscr-offset-from-ram-start holds the offset address of the
bootscript file from the start of the ram base in systems with RAM
detection.
