Add platform devices for the Mac IDE controller variants. Convert the
macide module into a platform driver to support two of those variants.
For the third, use a generic "pata_platform" driver instead.
This enables automatic loading of the appropriate module and begins
the process of replacing the driver with libata alternatives.

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore. Make sure the modular drivers in the ide dir
are actually calling out for <module.h> explicitly in advance.

Move the ack_intr() method into 'struct ide_port_ops', also renaming it to
test_irq() while at it...

There are now two methods that clear the port interrupt: ack_intr() method,
implemented only on M680x0 machines, that is called at the start of ide_intr(),
and clear_irq() method, that is called somewhat later in this function. In
order to stop this duplication, delegate the task of clearing the interrupt
to clear_irq() method, only leaving to ack_intr() the task of testing for the
port interrupt.

Remove hw_regs_t typedef and rename struct hw_regs_s to struct ide_hw.
There should be no functional changes caused by this patch.

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)
There should be no functional changes caused by this patch.

* 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.

* 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.

Remove some more cruft from machw.h and drop the #include where it isn't
needed.
