feat(tc): add memory node in the device tree

With new TC revisions, memory banks move around which requires an update
in platform_def. It also requires an update in the device tree which
doesn't come naturally. To avoid this, add the memory node such that it
uses the macros defined in platform_def.

By doing this we can put u-boot out of its misery in trying to come up
with the correct memory node and tf-a's device tree becomes complete.
