pnv_phb4_pec: Only export existing PHBs to the device tree

Browse source 
So far, we were always exporting all possible PHBs to the device
tree. It works well when using the default config but it potentially
adds non-existing devices when using '-nodefaults' and user-created
PHBs, causing the firmware (skiboot) to report errors when probing
those PHBs. This patch only exports PHBs which have been realized to
the device tree.

Fixes: d786be3fe7 ("ppc/pnv: enable user created pnv-phb for powernv9")
