YRabbit 85e7c68fc6 Gowin. BUGFIX. Fix multi-line descriptions. 
If let's say the enumeration of inputs took several lines, then all
after the first one were ignored. Since the first line ended with a
comma, an error was generated when trying to use the resulting file.

David Anderson af8e85b7d2 techlibs/lattice: add missing clock muxes to ECP5 block ram blackboxes 
prjtrellis documentation shows that EBR clock inputs have optional inverters.
The bram techmap outputs those parameters, and nextpnr consumes them. But for
whatever reason, Diamond doesn't include those parameters in its blackbox
models. This makes synth_lattice fail when targeting ECP5 with a design that
maps block RAMs if you include any pass that needs cells_bb_ecp5.v's definitions.

This change fixes up the ECP5 bram blackbox models at generation time, by
adding the missing parameters back in.

Martin Povišer 9018d06a33 quicklogic: Avoid carry chains in division mapping 
The default mapping rules for division-like operations (div/divfloor/
mod/modfloor) invoke subtractions which can get mapped to carry chains
in FPGA flows. Optimizations across carry chains are weak, so in
practice this ends up too costly compared to implementing the division
purely in soft logic.

For this reason arrange for `techmap.v` ignoring division operations
under `-D NODIV`, and use this mode in `synth_quicklogic` to avoid carry
chains for divisions.
