[PATCH] powerpc: Fix ide-pmac sysfs entry

[Benjamin Herrenschmidt]

It looks like the generic ide code now wants ide_init_hwif_ports() to
set the parent struct device into the ide_hw structure (new field ?).
Without this, the mac ide code can cause the ide probing code to explode
in flames in sysfs registration due to what looks like a stale pointer
in there (happens when removing/re-inserting one of the hotswap media
bays on some laptops).
