[PATCH] cirrusfb: update for amiga (zorro)

Cirrusfb updates:
  - Cirrusfb depends on Zorro or PCI
  - Revive Zorro support, using new Zorro driver framework
  - Merge PCI and Zorro code where possible
  - Use C99 initializers
  - Kill superfluous whitespace
  - #undef I/O ops before redefining them on Amiga
