OPAL/MPIPL: Processor Dump Area Table interfaces

This patch adds support to collect processor architected register data.

SBE <--> Hostboot :
-------------------
  During first boot, hostboot reserves memory to copy architected register
  data by SBE and sends address to each SBE (see commit 9f49d11b). During
  MPIPL SBE collects architected register data and copies to reserved
  memory.

Hostboot <--> Hypervisor :
--------------------------
  HDAT/SPIRAH has new ntuple (Processor Dump Area) to pass various
  architected register data. During IPL/runtime hypervisor reserves memory
  for architected register data and updates SPIRAH.

  During MPIPL (istep 14.8), hostboot converts SBE formated architected
  registers data to HDAT format and copies to hypervisor reserved memory.
  It uses NACA/SPIRAH pointers to get hypervisor reserved memory details.

  Hostboot has to update SPIRAH ntuple after loading new LID to memory.
  Hence this patch introdues below new attributes:
    - PDA_CAPTURED_THREAD_REG_ARRAY_ADDR
    - PDA_CAPTURED_THREAD_REG_ARRAY_SIZE
    - PDA_THREAD_REG_ENTRY_SIZE
    - PDA_THREAD_REG_STATE_ENTRY_FORMAT
