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

* ide-h8300

- 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.
