YRabbit 2a3720921c Gowin. Fix GW5A ADCs. 
For these primitives, Gowin decided to use a different option for
describing ports—directly in the module header, i.e.

``` verilog
module ADC(input CLK);
```

instead of
``` verilog
module ADC(CLK);
input CLK;
```

Since this one-time parser becomes too confusing, it is easier to simply
add ADC descriptions as they are from a separate file, especially since
these primitives are only available in the GW5A series.

Test:
``` shell
yosys -p "read_verilog top.v; synth_gowin -json top-synth.json -family gw5a"
```

The old version of Yosys simply won't compile the design due to the lack
of port descriptions, while the new version will compile without errors.

YRabbit 02e40e8118 Gowin. Reduce the range of flip-flop types. 
UG303-1.0E_Arora Ⅴ Configurable Function Unit (CFU) User Guide.pdf
specifies that the only flip-flop types supported in GW5 are DFFSE,
DFFRE, DFFPE, and DFFCE.

However, the bit streams generated by the vendor IDE also contain DFF
flip-flops, which are probably the result of optimisation, so we leave
them in the list of permitted items, but add a flag that will allow the
generation of completely correct output files, acceptable for further P&
R using vendor tools (they will not allow the use of flip-flops other
than the four specified in the netlist).

In the GW5 SemiDual Port BSRAM series, the primitive does not have
RESETA and RESETB ports—they are replaced by the RESET port, so we
separate the files for BSRAM generation, especially since in the future
we may have to take into account other, as yet unexplored, differences
in BSRAM.

YRabbit d60dc93e92 Gowin. Renaming inputs of the DCS primitive. 
The dynamic clock selection (DCS) primitive has undergone changes with
the release of the GW5A series—the CLK0,1,2,3 inputs are now
CLKIN0,1,2,3, but only for GW5A series chips.

There are no functional changes, only renaming.

Here we are transferring the description of the DCS primitive from
general to specialized files for each chip series.

We have also fixed a bug in the generation script that caused the loss
of primitive parameters. Fortunately, this only affected the
analog-to-digital converter, which has not yet been implemented.

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.
