YRabbit 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.

David Lanzendörfer d1b767ea8b Adding missing to Gowin tech files 
Without OSER4_MEM, IDES4_MEM and DQS the synthesis of my Rocket Chip
design for my Sipeed Tang FPGA fails.

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`.

YRabbit 79c5a06673 gowin: Fix SDP write enable port. 
This primitive does not have a separate WRE port, so we regulate writing
using Clock Enable.

YRabbit 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.
