powerpc: Remove alloc_maybe_bootmem for zalloc version
Replace all remaining callers of alloc_maybe_bootmem with
zalloc_maybe_bootmem. The callsite in pci_dn is followed with a
memset to clear the memory, and not zeroing at the other callsites
in the celleb fake pci code could lead to following uninitialized
memory as pointers or even freeing said pointers on error paths.
