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!

While at it also:
* Don't multilane for reg >= 8 bit width.
* Only check if we should switch to multilane after finding min field width.

Targets which lack an adjustable clocker will not expose the required
registers. Provide a stub sdclk_set_clk() routine for those situations.
