There's no need to have a sized array in the prototype, might as well

Host drivers using ide_register_hw() and 'initializing == 1':

* ide-pnp
  - depends on ISA

* ide_arm 
  - ARM arch specific
  - initialized before all other host drivers

* ide-cris
  - CRIS arch specific => IDE_ARCH_OBSOLETE_INIT is not defined
  - broken

* ide-h8300
  - H8300 arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI

* buddha/q40/gayle/macide/falconide
  - M68K arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI

Since the only host drivers which probe interfaces before the above ones are:

* ali14xx/dtc2278/ht6560b/qd65xx/umc8672
  - depend on ISA
  - require IDE_ARCH_OBSOLETE_INIT=y to work

* PCI ones
  - depend on PCI

don't try to unregister interfaces if 'initializing == 1' in ide_register_hw()
(it is possible that built-in host drivers will claim all IDE interfaces but
later ide-pnp host driver will try to unregister them - this change fixes it).

Also skip hwif->hold check if 'initializing == 1' since it is set only by:

* pmac
  - PPC && PMAC specific => no ISA

* au1xxx-ide
  - MIPS && SOC_AU1200 specific => no ISA

and use ide_find_port() helper to find free ide_hwifs[] slot.

* Make cris_dma_host_on() void.

I left fixing ide-cris after "kill dma_on/dma_off_quietly() methods"
patch because:

* Currently this driver is broken: cris_dma_on() (returns 'int')
  is assigned to hwif->dma_host_on (returns 'void') so the driver
  won't build.

* ->ide_dma_on method was missing so the driver OOPS-es on attempt
  to enable DMA.

* drive->using_dma was never set/cleared so DMA wouldn't be used anyway.

Unfortunately it seems that ide-cris stays broken even after this patch:

* V10: <asm/arch-v10/ide.h> needs fixing
  - ide_init_default_hwifs() should be removed
    (IDE core no longer uses it)
  - same for ide_init_hwif_ports() and ide_default_{irq,io_base}()
    (they shouldn't be needed for ide-cris host driver)

* V32: I'm unable to find a place which defines ETRAX_ARCH_V32

but I'm leaving fixing this to CRIS gurus. :)
