Factor out setting PCI bus-mastering from ide_hwif_setup_dma()
to ide_pci_set_master() helper.
While at it:
* don't read PCI Command register if not necessary
* use PCI device name instead of hwif->name
* cleanup ide_hwif_setup_dma() a bit

* Reserve PCI BARs 0-3 (0-1 for single port controllers) in
ide_pci_enable() and remove ide_hwif_request_regions() call
from ide_device_add_all() (also cleanup resource management
in scc_pata host driver).
* Fix handling of PCI BAR 4 in ide_pci_enable(), then cleanup
ide_iomio_dma() (+ init_hwif_trm290() in trm290 host driver)
and remove ide_release[_iomio]_dma().
v2:
* Fixup trm290 host driver.
v3:
* Because of scc_pata host driver changes we need to call
pci_request_selected_regions() also in setup_mmio_scc().

* Move ide_match_hwif() to ide-probe.c from setup-pci.c and rename

This function didn't actually check if a given BAR is in I/O space because of
using the bogus PCI_BASE_ADDRESS_IO_MASK (which equals ~3) to test the resource
flags instead of IORESOURCE_IO -- fix this, make ide_hwif_configure() check the
results failing if necessary, and move the printk() call to the failure path.

* Add 'const struct ide_port_info *d' argument to ide_device_add[_all]().

* Add IDE_HFLAG_NO_AUTOTUNE host flag for host drivers that don't enable

* Setup hwif->chipset in ide_init_port() but iff pi->chipset is set

This patch converts users of pci_enable_device_bars() to the new
pci_enable_device_{io,mem} interface.
The new API fits nicely, except maybe for the QLA case where a bit of
code re-organization might be a good idea but I prefer sticking to the
simple patch as I don't have hardware to test on.
I'll also need some feedback on the cs5520 change.

Delete filenames/versions from comments.
I'm leaving decisions about adding DRV_VERSION defines and MODULE_VERSION()-s
to maintainers of the respective drivers.
While at it:
* Remove unused VERSION define from ide.c.
* Remove unused/stale DRV_VERSION define from au1xxx-ide.c.

* Rename 'simplex_stat' variable to 'dma_stat' in ide_get_or_set_dma_base().
* Factor out code for forcing host out of "simplex" mode from
ide_get_or_set_dma_base() to ide_pci_clear_simplex() helper.
* Add IDE_HFLAG_CLEAR_SIMPLEX host flag and set it in alim15x3 (for M5229),
amd74xx (for AMD 7409), cmd64x (for CMD643), generic (for Netcell) and
serverworks (for CSB5) host drivers.
* Make ide_get_or_set_dma_base() test for IDE_HFLAG_CLEAR_SIMPLEX host flag
instead of checking dev->device (BTW the code was buggy because it didn't
check for dev->vendor, luckily none of these PCI Device IDs was used by
some other vendor for PCI IDE controller).

* ide_init_hwif_ports() call in setup-pci.c::ide_hwif_configure()
doesn't depend on the default cotrol register offset, default IRQ
or ppc_ide_md.ide_init_hwif implementations so ide_std_init_ports()
can always be used.
* Since 'base' is always non-zero and thus hwif->io_ports[IDE_DATA_OFFSET]
is also non-zero always clear hwif->noprobe.
