scsi: 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 it has stabilized move the common code into the core driver but don't build it unless needed. This replaces the inline assembler with more portable writesb() calls. Optimizing the m68k writesb() implementation is a separate patch.
