The function pnv_restore_hyp_resource() loads the TOC into r2 from
the invalid PACA pointer before fixing r13 value. This do not affect
POWER ISA 3.0 but it does have an impact on POWER ISA 2.07 or less
leading CPU to get stuck forever.

When was this broken ? Should this get backported to stable ?

Broken for 4.8-rc1 only after moving the SPRN_HSPRG0 checking to
idle_book3s.S. Hence no back ports needed.
