z20x: Performance Improvements

- boards/z80/ez80/z20x/scripts/z20x_*.linkcmd: Reduce from 4 to 1 wait state. That i sufficient because of the slow clocking of the eZ80F92 - boards/z80/ez80/z20x/src/w25_main.c: Replace CRC algorithm with simple, less time consuming check sum. - boards/z80/ez80/z20x/configs/nsh: Rename the nsh_ram configuration to just nsh - boards/z80/ez80/z80x/configs/hello: Add simpler program to make debugging the loader easier.
