[Skiboot] [PATCH 6/7] astbmc: Don't do P8 PSI or DT fixups on P9

[Oliver O'Halloran]

We do some P8 specific hacks on BMC platforms to work around Hostboot
not initialising the PSI BAR and to fix some problems in the hostboot
provided device tree. These shouldn't be done on P9.

Ben, I'm guessing the we need the PSI BAR setup on P8 for interrupts.
Do we need to do anything similar on P9?
