[PATCH RFC 07/11] powerpc/pci: Don't reduce the host bridge bus range

[Sergey Miroshnichenko]

Currently the last possible bus number of the PHB is set to the last
used bus number during the boot. So when hotplugging a bridge later,
no new buses can be allocated because they are limited by this value.

Let the host bridge contain any number of buses up to 255.
