Icenowy Zheng 291c43b898 sipeed_tang_nano_20k: new board
This board uses Gowin GW2AR series chip (which is GW2A with integrated
RAM).

Support for the integrated SDRAM on Tang Nano 20K is still TODO.

Note: currently when the SD card is enabled, block 0 could be correctly
read but block 1 will fail.
