Subject[PATCH 00/18] ide: warm-plug support for IDE devices and other goodies

- couple of fixes and preparatory patches

- rework of PowerMac media-bay support ([un]register IDE devices instead of
[un]registering IDE interface) [ it is the main reason for spamming PPC ML ]

- IDE warm-plug support (though it is still experimental it should work fine,
unlike the older method), to warm-plug devices on a port 'idex':

# echo -n "1" > /sys/class/ide_port/idex/delete_devices
unplug old device(s) and plug new device(s)

# echo -n "1" > /sys/class/ide_port/idex/scan
done

- ability to add new interfaces for ide-generic host driver through
/sys/class/ide_generic/add, i.e.

echo -n "0x168:0x36e:10" > /sys/class/ide_generic/add
- because of the above changes some obsoleted/broken code can be removed
(thus the total effect of the patch series is -100 LOC)
