SaxonSoc Add support for the Fomu board

It would be awesome if the SaxonSoC supported the Tomu FPGA (Fomu). This would be an awesome introduction into to pure SpinalHDL design.

Happy to send people boards.

Fomu has been supported for some time - see https://github.com/SpinalHDL/SaxonSoc/blob/dev/hardware/scala/saxon/board/fomu/FomuMinimal.scala

I was planning to add support for Xip on the board as well and asked Sean Cross a question about how to get the Risc-V program into flash memory, but then I got my Ulx3s boards and have been mainly working on Linux on those.

Other operating systems such as Zephyr of FreeRTOS might run using SaxonSoc on the board.

Would probably need to update it. @lawrie Is the ram inferred using the big 32 KB blocks ?

It seems Fomu is using BmbOnChipRamGenerator instead of BmbIce40SpramGenerator. The later is being used only by Ice40up5kbevn.
