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

YRabbit 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`.
