This patch reverts commit 407d418f2fd4 ("powerpc/chrp: Move PHB
discovery") and commit 9634afa67bfd ("powerpc/chrp: Make hydra_init()
static").

Running the upstream kernel on Qemu's brand new "pegasos2" emulation
results in a variety of backtraces such as

...and actually using it appears to require both manually enabling it
in the qemu config and finding a random bios blob that is no longer
distributed by the manufacturer. Cool.

That is absolutely wrong. vof.bin provided by qemu in the linux root
directory works just fine, plus chrp32_defconfig minus SMP.
