fbdev/cirrusfb: Add support for Picasso IV in Zorro II mode
In Zorro II mode, the Village Tronic Picasso IV graphics card shows up as
either 2 or 3 Zorro devices:
- One for the registers of the Cirrus Logic graphics chip,
- One for the first bank of 2 MiB of graphics memory,
- An optional one for the second bank of 2 MiB of graphics memory,
if there was enough free Zorro II address space.
Based on src/sys/arch/amiga/dev/grf_cl.c from NetBSD.
