ARM: 9010/1: uncompress: Print the location of appended DTB

When using the kernel with an appended DTB it is useful to
know where this will end up in the physical memory at the
time the kernel boots.

We add a debug print macro that will help out with this.
Here is a sample debug print after passing -DDEBUG to head.S
during compilation:

DTB:0x40CEBA70 (0x000051B5)
C:0x402080C0-0x40CF0CE0->0x41801D00-0x422EA920
DTB:0x422E56B0 (0x00005262)

This means that the appended DTB is first found after the
compressed kernel at 0x40CEBA70 of size 0x51B5 and then
after the compressed kernel is moved to 0x41801D00
it is found again at 0x422E56B0 and is there size 0x5262.

The growth in size of the FDT is due to the call to
atags_to_fdt() that augments the DTB with ATAG information.
