It *could*. Just felt a little weird to artificially restrict the usable memory
because the stack just barely runs into one of our reserved regions long enough
to break a dt reserved-memory allocation.

Initially this was proposed because there are multiple runtimes with their own
allocation techniques that could potentially take advantage of that space. If
it's still preferable to use board_get_usable_ram_top though I will change it.
