YRabbit 1871afe9b9 Gowin. Taking into account the features of ROM
For pROM(X9) primitives in images generated by Gowin IDE, there is an
interesting recommunication of inputs depending on the data bit depth.
For example, in some cases, a high logical level may be applied to the
Write Enable input, which, let’s say, is not entirely usual for Read
Only memory.

Here we will do similar manipulations.

In addition, several minor bug fixes are included:

 - Fixed bit numbering for non-X9 series primitives.
 - Fixed decoder generation for BLKSEL - do not assume unused inputs are
   connected to GND.
 - Use default values for BSRAM parameters - don't assume their
   mandatory presence.
