Subject[PATCH] cirrusfb: update for amiga (zorro)
Hey Geert, 

Thanks for bringing the ZORRO paths up to date for the cirrusfb driver.
The code looks good, and I trust your knowledge of Amiga much more than
my own. It would be nice if someone actually has this hardware and can
test the patch... Anyone? Anyone? Lars? Beuler?

There was a trivial problem applying the patch - one of the whitespace
fixes choked, so I took it out of the patch (below).

-dte

---

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
