This makes random problem related to assembling big kernels go away! But
it also make SD card reading much slower...

sdc: implement CRC7 computation on cmds
...
For now, this achieves nothing else than wasting cycles, but this is the
first step in enabling CRC verifications (CMD59).
I think that this is where my random problems with assembling large
kernels from SDC come from: bad data that isn't detected. If that
happens when PGM loads programs in memory, then anything can happen.
`sdct`, when ran often enough, will error out or corrupt away (go
crazy)...
