YRabbit 79c5a06673 gowin: Fix SDP write enable port. 
This primitive does not have a separate WRE port, so we regulate writing
using Clock Enable.

YRabbit ae991abf2e gowin: fix the BRAM mapping. 
The primitives used have been corrected and changes have been made to the set of signals.
The empirically established need to set the OCEx signal to 1 when using READ_MODE=0 is reflected.

Martin Povišer 16ea497d7c pmgen: Have a single make pattern 
Remove duplicate %.pmg -> %_pm.h pattern. One of the duplicates overrode
the other, and in some conditions there were build races as to whether
the target directory for the generated header would exist. Instead have
a single rule which is properly generalized.

Martin Povišer fed2720999 synth_lattice: Optimize flip-flop memories better 
After `memory_map` maps memories to flip-flops we need to let `opt`
remove undef muxes, otherwise we block enable/reset signal inference by
`opt_dff` which is in detriment to QoR.

Martin Povišer ee3a4ce14d synth_lattice: Merge NOT gates on DFF control signals 
`dfflegalize` will emit NOT gates to drive control signals on flip-flops
when mapping to supported flip-flop polarities. Typically in a design
this will produce a number of NOT gates driven by the same signal. For
one reason or another ABC doesn't fully cancel this redundancy during
LUT mapping. Insert an explicit `opt_merge` pass to improve synthesis
QoR.
