Announce locations of memory objects

To make it easier to debug boot failures, log the location of memory
objects at boot time.

This is logged to the serial console as:

| Boot-wrapper v0.2
| Entered at EL3
| Memory layout:
| [0000000080000000..0000000080001f90] => boot-wrapper
| [000000008000fff8..0000000080010000] => mbox
| [0000000080200000..00000000822af200] => kernel
| [0000000088000000..0000000088002857] => dtb
