powerpc: Drop zalloc_maybe_bootmem()
The only callers of zalloc_maybe_bootmem() are PCI setup routines. These used to be called early during boot before slab setup, and also during runtime due to hotplug. But commit 5537fcb319d0 ("powerpc/pci: Add ppc_md.discover_phbs()") moved the boot-time calls later, after slab setup, meaning there's no longer any need for zalloc_maybe_bootmem(), kzalloc() can be used in all cases.
