[Skiboot] [PATCH v9 0/2] Add SBE driver support

[Vasant Hegde]

This patchset adds support to communicate to SBE.

Patch 1 adds primary property to xscom node. Its used to detect master SBE.
Patch 2 adds base SBE driver.

Changes in v9:
  - As BenH suggested changed interrupt handler code to process one
    bit at a time.
  - Also added logic in interrupt handler code to detect unhandled
    interrupt bits.

Changes in v8:
  - Addressed Ben's review comments on v7
  - Major onces:
    - Fixex p9_sbe_msg_complete()
    - Removed inline function to update sbe state
    - Fixed interrupt handler code

Changes in v7:
  - Addressed Ben's review comments
  - Major onces :
    Separate response message
    Reoganization of poller and interrupt handler code
    Convert recursion to loop
    Fixing return value issues

Changes in v6:
  - I need base driver support for MPIPL as well. Hence I've split
    base driver and timer support to separate patchset.
  - Reworked base driver code based on Ben's review comment.
  - Using new HDAT property to detect master chip SBE

Changes in v5:
  - Rebased on top of upstream master
  - Synced to latest SBE-Host spec
  - Fixed sbe_sync_msg()
  - Removed continous timer call

Changes in v4:
  - Used PNOR info idata pointer to find primary chip
  - Fixed few return value issues

Testing:
  - Tested this patchset on P9 system and it working fine.
