arch-arm, configs: Treat the bootloader rom as cacheable memory
Prior to this changeset the bootloader rom (instantiated as a
SimpleMemory) in ruby Arm systems was treated as an IO device and it
was fronted by a DMA controller. This changeset moves the bootloader
rom and adds it to the system as another memory with a dedicated
directory controller.
