m68k/mac/: possible cleanups

This patch contains the following possible cleanups:
- make the following needlessly global code (always) static:
  - baboon.c: struct baboon
  - baboon.c: baboon_irq()
  - config.c: mac_orig_videoaddr
  - config.c: mac_identify()
  - config.c: mac_report_hardware()
  - config.c: mac_debug_console_write()
  - config.c: mac_sccb_console_write()
  - config.c: mac_scca_console_write()
  - config.c: mac_init_scc_port()
  - oss.c: oss_irq()
  - oss.c: oss_nubus_irq()
  - psc.c: psc_debug_dump()
  - psc.c: psc_dma_die_die_die()
  - via.c: rbv_clear
- remove the unused bootparse.c
- #if 0 the following unused functions:
  - config.c: mac_debugging_short()
  - config.c: mac_debugging_long()
- remove the following unused code:
  - config.c: mac_bisize
  - config.c: mac_env
  - config.c: mac_SCC_init_done
  - config.c: mac_SCC_reset_done
  - config.c: mac_init_scca_port()
  - config.c: mac_init_sccb_port()
