[Skiboot] [PATCH] phb5: Remove obsolete capp-related properties

[Frederic Barrat]

This patch removes the following properties from PHB entries in the
device tree on P10, since there's no CAPP any more and the properties
no longer make sense:
ibm,phb-indications
ibm,capp-timebase-sync
ibm,capi-flags

It has no effect on linux: some were already ignored and others won't
even be read since the cxl driver (the only consumer) already fails
early on P10.
