Improvements for gowin support

Pepijn de Vos 8ab412eb16 Remove dff init altogether
The hardware does not actually support it.
In reality it is always initialised to its reset value.

This adds simulation models for the following primitives:

- MULT18X18 and MULT18X18S (Virtex 2*, Spartan 3)
- MULT18X18SIO (Spartan 3E, Spartan 3A)
- DSP48A (Spartan 3A DSP) — implemented in terms of DSP48A1
- DSP48A1 (Spartan 6)

whitequark 3c643c57df write_verilog: add -extmem option, to write split memory init files.
