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

Nowadays it is not worth having a separate config option for
Amiga IDE Doubler support so always include it (it still needs
to be explicitly enabled by module parameter).

* 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.

If IDE doubler is used ports need to be serialized. Currently
init_irq() handles it fine but lets also set IDE_HFLAG_SERIALIZE
host flag explicitly in preparation for future changes.
Also convert the driver to use struct ide_port_info while at it.
