Benjamin Herrenschmidt bf7def5503 soc: Don't require dram wishbones signals to be wired by toplevel
Currently, when not using litedram, the top level still has to hook
up "dummy" wishbones to the main dram and control dram busses coming
out of the SoC and provide ack signals.

Instead, make the SoC generate the acks internally when not using
litedram and use defaults to make the wiring entirely optional.
