sandbox: remap memory load addresses

The existing memory layout places the bloblist at 0xb000 and the fdt at
0x100, resulting in a 0xaf00 size constraint for the fdt. This constraint
has been reached. Lets modify the layout by moving the bloblist to 0x100,
device tree to 0x1000 and placing early memory allocation after pre-console
buffer at 0xf4000. This should guarantee sufficient memory allocation for
future expansion.
