There should be no functional changes caused by this patch.
Brr... seems to complicate the bookkeeping a lot...
I looked at the m68k drivers only:

Another magic constant, hws[] always has 4 elements?
idx[] / hws[] always has 4 elements if used with ide_device_add().
[ Todays' patches will remove idx[] so the number of magic constants
will remain constant. :) ]

Q40IDE_NUM_HWIFS
I revised the patch, thanks!
From: Bartlomiej Zolnierkiewicz <bzolnier@xxxxxxxxx>
Subject: [PATCH] ide: pass hw_regs_t-s to ide_device_add[_all]() (take 2)
* Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert
host drivers + ide_legacy_init_one() + ide_setup_pci_device[s]() to use
it instead of calling ide_init_port_hw() directly.
[ However if host has > 1 port we must still set hwif->chipset to hint
consecutive ide_find_port() call that the previous slot is occupied. ]
* Unexport ide_init_port_hw().
v2:
* Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c.
(Suggested by Geert Uytterhoeven)
* Better patch description.
There should be no functional changes caused by this patch.
