Unfortunately that conversion cannot happen right now, as zorro8390.c
already binds against the X-Surf zorro device.
I think the proper solution would be to start using MFD for multi-function
Zorro devices, cfr. the work I started years ago, but never completed
https://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k.git/log/?h=zorro-mfd
Then the Buddha MFD driver can instantiate 2 Buddha IDE cells, the
Catweasel MFD driver can instantiate 3 Buddha IDE cells and a Catweasel
floppy cell, and the X-Surf MFD driver can instantiate 2 Buddha IDE
cells and a zorro8390 cell.
