[PATCH] restore parport_pc probing on powermac
The last change for partport_pc did fix the common case for all PowerMacs,
but it broke the case for PCI multiport IO cards. In fact, the config
option CONFIG_PARPORT_PC_SUPERIO=y lead to a hard crash when cups probed
the parport driver. It enables the winbond and smsc probing.
Remove the PARPORT_BASE check again, parport_pc_find_nonpci_ports() will
take care of it. All powerpc configs should have
CONFIG_PARPORT_PC_SUPERIO=n, the code did not find anything on the chrp
boards we tested it on.
Tested on a G4/466 with a PCI card:
