Add board definition and FPGA part ID for the MILIANKE S200 EG4D20
development board. Also update related documentation and outdated URL.
Tested ok by loading bitstream to SRAM and FLASH.

Programming to SRAM works. Programming flash works with a renamed
spiOverJtag bitfile - cs(g)484 is different from fg(g)484, but the
configuration flash IOs all end up on the same pads in the end.
- copy dirtyjtag to esp_usb_jtag, it compiles
- copy protocol definiton, defines and private data/struct from openocd esp_usb_jtag.c
- ulx3s_esp board with esp32s3 cable
- esp_usb_jtag specify usb vid:pid in jtag.cpp
- hardcode usb interface and endpoints
- getting caps
- set chip id (not applicable for fpga)
- tms write done, untested
- cleanup and toggle clk
- 32bit counting
- setting divisor (todo read base freq)
- div range within 1-255
- base speed from descriptor
- fix doc typo with swapped tms/tdi some cleanup but it doesn't work.
as at 6MHz the download of bitstreams is not stable.
With "not stable" we mean that:
- when dealing with Certus/Crosslink, most of the times it works
- when dealing with CertusPro devices, most of the times it doesn't work
We think this is due to the size of the bitstream and the way that the
transmission/storing is handled on the receiving side (i.e. the FPGA).
Fix to lattice programming:
we considered a svf file generated by Lattice Radiant-Programmer
and compared it with the current way lattice devices were programmed.
There were few differences dealing with configuration reset and REFRESH.
These fixes allow us to program an fpga when it is in a state
of error (e.g. there's no bitstream in the SPI Flash).
Lattice parts added:
- CertusPro FPGA
Nexus boards added:
- Certus Versa Evaluation board
- CertusPro Evaluation board
- CertusPro Versa Evaluation board
