* Return 0 instead of dev->irq in ->init_chipset implementations.
* Fix ->init_chipset method to return 'int' value instead of
'unsigned int' one.
This fixes ->init_chipset handling for host drivers (cs5530, hpt366
and pdc202xx_new) for which it is possible for this method to fail.

Move apparently misplaced read_sff_dma_status() method from 'struct ide_tp_ops'
to 'struct ide_dma_ops', renaming it to dma_sff_read_status() and making only
required for SFF-8038i compatible IDE controller drivers (greatly cutting down
the number of initializers) as its only user (outside ide-dma-sff.c and such
drivers) appears to be ide_pci_check_simplex() which is only called for such
controllers...

Replace setting of 'hwif->dma_ops' in the 'alim15x3' and 'palm_bk3710' drivers'
init_dma() methods with initializing the corresponding member of their 'struct
ide_port_info' instances and remove such setting from the 'hpt366' driver that
just doesn't use 'sff_dma_ops'. Along with some code save, this prepares us for
the next patch...

* hpt366: set IDE_HFLAG_SERIALIZE in ->host_flags if needed
in init_hwif_hpt366(). Remove HPT_SERIALIZE_IO while at it.
* Set IDE_HFLAG_SERIALIZE in ->host_flags if needed in
ide_init_port().
* Convert init_irq() to use IDE_HFLAG_SERIALIZE together with
hwif->host to find out ports which need to be serialized.
* Remove no longer needed save_match() and ide_hwif_t.serialized.
v2:
* Set host's ->host_flags field instead of port's copy.
This patch should fix the incorrect grouping of port(s) from
host(s) that need serialization with port(s) that happen to use
the same IRQ(s) but are from the host(s) that don't need it.
