c37db637c7 Gowin. Remove unnecessary modules 
Primitives that are not planned for implementation for reasons of
belonging to old unsupported chips or representing composite complex IPs
rather than primitives are removed.
Also latches and large MUXes not planned for implementation.

ab35dff702 Gowin. Add the EMCU primitive. 
EMCU is a micro-processor based on ARM Cortex-M3 embedded in the
GW1NSR-4C chip used in the Tangnano4k board.

19bbdd8800 Gowin. Add the DCS primitive 
Not so much adding the primitive itself, but only its DCS_MODE
parameter, without which an error occurs.

9d0bca9775 Gowin. Add an energy saving primitive 
We add a BANDGAP primitive used to turn off power to OSC, PLL and other
things on some GOWIN chips.

We also mark this primitive and GSR as keep.

Fix some synth_* help messages 
Mostly memory_libmap arg checks; puts the checks into an else block on the `if (help_mode)` check to avoid cases like `synth_ice40` listing `-no-auto-huge [-no-auto-huge]`.
Also fix `map_iopad` section being empty in `synth_fabulous`.

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.
