dt/flattree: Return virtual address from early_init_dt_alloc_memory_arch()
The physical address is never used by the device tree code when allocating memory for unflattening. Change the architecture's alloc hook to return the virutal address instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
