Fix off-by-one error on almost full condition for prefetch

This causes a DRC error on the Xilinx tools when the prefetch
lines setting is 1. Don't know why this wasn't caught earlier,
but it just popped up in CI.

Reclock spi sdcard access after initialisation
...
Depends upon https://github.com/enjoy-digital/litex/pull/435
After initialising the card, reclock the card, aiming for ~16MHz (divider is rounded up, as slower speed is safer), but a maximum of half of the processor speed.
Tested with the card being clocked to 12.5MHz on de10nano

On 64-bit architectures (e.g., Rocket), 'unsigned long' means
eight (not four) bytes. Use 'unsigned int' wherever a FAT data
structure requires a four-byte field!

Now we only generate multilane bitfield documentation when the CSR has
fields, and the smallest field is less than 8bit long. As this is when
we start running into space problems with the field names.
