A short series with some cleanup around user-created PHB. The main point is to remove errors seen from the firmware (skiboot) when using user-created PHBs, as we were always showing all the default PHBs in the device tree, so skiboot tried to probe non-existing devices. The first 2 patches allow to only export the user-created PHBs in the device tree when 'nodefaults' is used. The last 2 are more cosmetic and moving code around where it makes more sense.
I'm aware of Phil's comments in patch 1 and the solution can probably be improved on (as with any other solution and code). Patch 1 is a requirement to the actual fix in patch 2 though, and Phil's comments applies to more stuff in the current pnv-phb code. Since we can handle design changes later on while still fixing the bug, I queued all these for 8.0. Thanks, Daniel
