Patrick Urban 0d871b6c49 synth_gatemate: Add block RAM cascade support 
* add simulation model for block RAM cascade in 40K mode
* limit 20K_SDP and 40K_SDP to 40 and 80 bits (the only useful configurations)

Patrick Urban 4bee908ae8 synth_gatemate: Revise block RAM read modes and initialization 
* enable mixed read-width / write-width ports in SDP mode
* fix NO_CHANGE and WRITE_THROUGH behavior during read access
* remove redundant zero-initialization
* set A/B_WE bit during map (gatemate_bramopt pass could be removed later)
* differentiate "upper" and "lower" initialization for cascade mode

* remove `MAXWIDTH` parameter and treat both vector widths individually in `mult_map.v`
* iterate over all modules in `gatemate_bramopt` pass
