refactor(tc): move DTB to start of DRAM

Now that tf-a passes the DTB address to BL33, its location doesn't
matter. Since we declare a fixed size for it (32K) put it at the start
of ram to not fragment memory. This has the added benefit of
"supporting" larger kernel sizes which are breaking with the current
location.
