335f877d66 Run simulation with verilog sd emulator
This also slowed the cpu clock down, we should speed it up again

61f6e53327 Updates based on fpga test
1. in SD mode, CMD0 does not have a response, so we specifically ignore
   it.

2. The penable signal was messed up, although it looks like this doesn't
   matter anyway

3. The SD clock should be out of phase from the data signal by 180
   degrees, so that we get max hold time
