Gregory Nutt ef604f8d43 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.
