[PATCH 5/6] esp_scsi: De-duplicate PIO routines

As a temporary measure, the code to implement PIO transfers was duplicated in zorro_esp and mac_esp. Now that this code has stabilized, move it into the core driver to eliminate the duplication. This replaces the inline assembler with more portable writesb() calls. Optimizing the m68k writesb()
