[Skiboot] [PATCH V2 0/2] Support runtime OCC reset/load in ZZ

[Shilpasri G Bhat]

This patch series provides support for runtime OCC reset/load in ZZ.
HBRT routines to reset/load/start OCC will be invoked via host
opal-prd. The FSP mbox events to reset/load/start OCC will be
forwarded to opal-prd and the status from HBRT will be returned back
to FSP.

Changes from V1:
- Add FSP specific occ reset opal_prd_msg_type to differentiate OCC
  reset from opal-prd v/s FSP-TMGT as FSP-TMGT OCC reset requires
  reset status to be returned from HBRT to FSP.
- Make OCC reset/load calls to loop over chip-ids in opal-prd in one
  shot instead of doing it per-chip. This is to reset/load the OCCs
  uniformly from one state to other.

  opal-prd: occ: Add support for runtime OCC load/start in ZZ
