c13b34f20e gowin: Himbaechel. Add BSRAM for all chips. 
The following primitives are implemented for the GW1N-1, GW2A-18,
    GW2AR-18C, GW1NSR-4C, GW1NR-9C, GW1NR-9 and GW1N-4 chips:

    * pROM     - read only memory - (bitwidth: 1, 2, 4, 8, 16, 32).
    * pROMX9   - read only memory - (bitwidth: 9, 18, 36).
    * SDPB     - semidual port    - (bitwidth: 1, 2, 4, 8, 16, 32).
    * SDPX9B   - semidual port    - (bitwidth: 9, 18, 36).
    * DPB      - dual port        - (bitwidth: 16).
    * DPX9B    - dual port        - (bitwidth: 18).
    * SP       - single port      - (bitwidth: 1, 2, 4, 8, 16, 32).
    * SPX9     - single port      - (bitwidth: 9, 18, 36).

    For GW1NSR-4C and GW1NR-9 chips, SP/SPX9 primitives with data widths
    of 32/36 bits are implemented using a pair of 16-bit wide
    primitives.

90d4863dd4 gowin: Himbaechel. Add GW1NZ-1 BSRAM. 
The following primitives are implemented for the GW1NZ-1 chip:

* pROM     - read only memory - (bitwidth: 1, 2, 4, 8, 16, 32).
* pROMX9   - read only memory - (bitwidth: 9, 18, 36).
* SDPB     - semidual port    - (bitwidth: 1, 2, 4, 8, 16, 32).
* SDPX9B   - semidual port    - (bitwidth: 9, 18, 36).
* DPB      - dual port        - (bitwidth: 16).
* DPX9B    - dual port        - (bitwidth: 18).
* SP       - single port      - (bitwidth: 1, 2, 4, 8, 16, 32).
* SPX9     - single port      - (bitwidth: 9, 18, 36).

Also:
 - The creation of databases for GW1NS-2 has been removed - this was not
   planned to be supported in Himbaechel from the very beginning and
   even examples were not created in apicula for this chip due to the
   lack of boards with it on sale.
 - It is temporarily prohibited to connect DFFs and LUTs into clusters
   because for some reason this prevents the creation of images on lower
   chips (placer cannot find the placement), although without these
   clusters the images are quite working. Requires further research.
 - Added creation of ALU with mode 0 - addition. Such an element is not
   generated by Yosys, but it is a favorite vendor element and its
   support here greatly simplifies the compilation of vendor netlists.
