powerpc: move find_and_init_phbs() to pSeries specific code
Previously, find_and_init_phbs() was used in both PowerNV and pSeries setup. However, since RTAS support has been dropped from PowerNV, we can move it into a platform-specific file. Signed-off-by: Daniel Axtens <dja@axtens.net> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
