Make CSR documentation diagrams, with more than 8 bits, be split into multiple lanes.

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.

cores/clock: simplify Fractional Divide support on S7MMCM.

Specific clkoutn_divide_range can now be provided by specialized XilinxClocking classes.
When provided, the specific range will be used. Floats are also now supported in the
range definition/iteration.

software: revert LTO changes (Disable it).
...
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.
- seems to cause issues with some litex-buildenv configurations. (see https://github.com/enjoy-digital/litex/issues/417 ).

soc/cores/spi_opi: documentation fixes
...
The ModuleDoc-generated documentation for the spi_opi module produced
slightly invalid output due to ambiguities in how rst assigns headers.
As a result, sections from the spi_opi document would appear as full
sections.
This cleans up these errors so that it parses properly under sphinx.

add fractional division options to clk0 config on PLL

S7 MMCMs allow fractional divider on clock 0. Add a fallback
to try fractional values on clock 0 if a solution can't be found.
This is necessary for e.g. generating both a 100MHz and 48MHz
clock from a 12MHz source with margin=0
