make ppc32 OFW usage on par with sparc64, make appropriate modifications elsewhere

introduce ofw_tree_walk_by_device_type() to gather all OFW devices of a given type
ppc32 uses canonized OFW tree, mac-io and display devices are detected in kernel (not by the boot loader) by means of device type
various busses (PCI, EBUS, etc.) stay sparc64 specific for now
boot memcpy() is defined in a common way
BALLOC_MAX_SIZE is platform-dependent
ppc32 and sparc64 boot loaders cleanup (removal of obsolete stuff, data is not passed by global variables if not necessary, etc.)
balloc and OFW tree canonizer have now a provision to support different mapping of the data during boot time and kernel run-time
OFW tree canonizer uses balloc_rebase() to store pointers suitable for access during kernel run-time (with potentially different memory mapping than during boot time)
