The legay ide driver has been replace with libata starting in 2003 and has
been scheduled for removal for a while.  Finally kill it off so that we
can start cleaning up various bits of cruft it forced on the block layer.

Recent pci_assign_irq() changes uncovered a problem with missing freeing of
PCI BARs on PCI IDE host initialization failure:

  ide0: disabled, no IRQ
  ide0: failed to initialize IDE interface
  ide0: disabling port
  cmd64x 0000:00:02.0: IDE controller (0x1095:0x0646 rev 0x07)
  CMD64x_IDE 0000:00:02.0: BAR 0: can't reserve [io  0x8050-0x8057]
  cmd64x 0000:00:02.0: can't reserve resources
  CMD64x_IDE: probe of 0000:00:02.0 failed with error -16

Fix the problem by adding missing freeing of PCI BARs to
ide_setup_pci_controller() and ide_pci_init_two().

They were getting this implicitly by an include of module.h
from device.h -- but we are going to clean that up and break
that include chain, so include export.h explicitly now.

Pass number of ports to ide_host_{alloc,add}() and then update
all users accordingly.

v2:
- drop no longer needed NULL initializers in buddha.c, cmd640.c and gayle.c
  (noticed by Sergei)

* 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

* Add ->irq_flags field to struct ide_port_info and struct ide_host.

* Update host drivers and IDE PCI code to use ->irq_flags field.

* Convert init_irq() and ide_intr() to use host->irq_flags.

This fixes handling of shared IRQs for non-PCI hosts
and removes ugly ifdeffery from core IDE code.
