Anton Blanchard 6cbf456388 SOC memory wishbone should clear ACK regardless of STB
The memory wishbone doesn't clear ACK and move the state machine on
until STB is de-asserted. This seems like it isn't compliant with
the spec and results in a maximum throughput of 1 transfer every
3 cycles.

Fixing this improves the situation to one transfer every 2 cycles.

Benjamin Herrenschmidt d21ef5836d Pass wishbone record to bram memory module
(And rename it to mw_soc_memory).

This makes soc.vhdl simpler and provides the same interface as
the simulated memory, which will help when sharing soc.vhdl
with sim later
