[POWERPC] iSeries: Move detection of virtual tapes
Now we will only have entries in the device tree for the actual existing devices (including their OS/400 properties). This way viotape.c gets all the information about the devices from the device tree. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
