[PATCH 5/5] powerpc/powernv: Remove set but not used variable 'parent'

[zhengbin]

Fixes gcc '-Wunused-but-set-variable' warning:

arch/powerpc/platforms/powernv/pci-ioda.c: In function pnv_ioda_configure_pe:
arch/powerpc/platforms/powernv/pci-ioda.c:867:18: warning: variable parent set but not used [-Wunused-but-set-variable]

It is not used since commit b131a8425c34 ("powerpc/powernv:
Set PELTV for compound PEs")
