Make powernv, pseries, powermac and maple use ppc_mc.discover_phbs.
These platforms need to be done together because they all depend on
pci_dn's being created from the DT. The pci_dn contains a pointer to
the relevant pci_controller so they need to be created after the
pci_controller structures are available, but before PCI devices are
scanned. Currently this ordering is provided by initcalls and the
sequence is:
1. PHBs are discovered (setup_arch) (early boot, pre-initcalls)
2. pci_dn are created from the unflattended DT (core initcall)
3. PHBs are scanned pcibios_init() (subsys initcall)
The new ppc_md.discover_phbs() function is also a core_initcall so we
can't guarantee ordering between the creation of pci_controllers and
the creation of pci_dn's which require a pci_controller. We could use
the postcore, or core_sync initcall levels, but it's cleaner to just
move the pci_dn setup into the per-PHB inits which occur inside of
.discover_phb() for these platforms. This brings the boot-time path in
line with the PHB hotplug path that is used for pseries DLPAR
operations too.

[mpe: Squash powermac & maple in to avoid breakage those platforms,
convert memblock allocs to use kmalloc to avoid warnings]

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
