Thomas Watson fea73d932e soc/cores/clock/intel: speed up PLL config computation
Caching the list of clock divisors to test speeds up computation by
about a factor of three.

Thomas Watson b7ef989963 soc/cores/clock/intel_*: respect PFD input frequency
Only use input clock divisors which respect the device limitation for
the phase-frequency detector's input frequency. This avoids errors where
Quartus complains the PLL parameters are invalid and refuses to
implement it.

The supported PFD frequencies in integer mode have been verified against
each family's datasheet. The unsupported-by-LiteX fractional frequency
information is removed for clarity.

As a bonus, this speeds up PLL config computation by several times.

Thomas Watson d531a07719 build/altera: fix clock constraints
This fixes two issues that prevented clock constraints (e.g.
"add_false_path_constraint") from working properly in Quartus.

The first fix passes the "keep" synthesis attribute through to the
generated Verilog in a way Quartus can understand.

The second fix tells Quartus to name PLL clocks according to their net
instead of the physical pin name by passing the "use_net_name" flag to
"derive_pll_clocks" in the .sdc file. Combined with the above, PLL
clocks will now be named according to the kept net.

This fix has been verified on Quartus Prime Lite 20.1.1.720.

`LitexFullQConfig`, respectively).

Gabriel Somlo 441042bef4 yosys_nextpnr_toolchain: add flow3 option to abc9 mode
Add "flow3" option to abc9 mode. This runs FPGA mapping several times,
producing a generally better mapping at the cost of increased runtime
(see https://github.com/Ravenslofty/yosys-cookbook/blob/master/ecp5.md).

Also, add a "--yosys-flow3" build option to both "trellis" and "oxide".

This is useful to abstract interfaces and propagate address_width.

Idealy, Wishbone should be fully switch to byte addressing since word addressing
has been a source of common issues/errors in the past but compatibility issues
would need to be evaluated first.
