software/libbase/spisdcard: fix 4-byte FAT fields on 64-bit CPUs
...
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.

Add bit more logic to decide when to switch to multilane CSR documentation.
...
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.

Split CSR documentation diagrams with more than 8 bits into multiple lanes.
...
In cases when each CSR bit has a name and we use CSR with more than 8
bits, the register diagram quickly becomes crowded and hard to read.
With this patch we split the register into multiple lanes of 8 bits
each.

It seems LTO is not yet fully working with all configurations, so it's better
reverting the changes for now.
- cause issues with LM32 available compilers.
- seems to cause issues with min/lite variant of VexRiscv.
