YRabbit 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.
