[PATCH 12/22] ppc64: RPA PHP cleanup

[linas <linas@austin.ibm.com>]

12-rpaphp-cleanup.patch

This patch cleans up some rpa dlpar code. Basically, 
the rpaphp_config_pci_adapter() was a wrapper routine, which
made two calls, and wrapped a bunch of verbose no-op code
around it.  This was consolidated wih the routine it called.
