[PATCH 5/7] ide: remove chipset field from hw_regs_t

From: Bartlomiej Zolnierkiewicz
Date: Wed May 13 2009 - 16:48:59 EST

* Convert host drivers that still use hw_regs_t's chipset field to use
the one in struct ide_port_info instead.

* Move special handling of ide_pci chipset type from ide_hw_configure()
to ide_init_port().

* Remove chipset field from hw_regs_t.

While at it:
- remove stale comment in delkin_cb.c

There should be no functional changes caused by this patch.
