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.

arch/z80/src/ez80: Fix eZ80F92 Interrupt Controller The eZ80F92 interrupt controller is very different from the eZ80F91. The eZ80F91 has: 1. Four byte interrupt vectors 2. The vector base address register is 16-bit so the vector table can lie in RAM Whereas the eZ80F92 has: 1. Two byte interrupt vectors 2. An 8-bit vector base address This means that the vectors must lie in the first 16-bits of FLASH and there must be a "trampoline" to get to interrupt handlers outside of the first 64-Kb of FLASH.
