SGPE and CME scanning integration

- Enable FAPI2 targets (move to .C)
- Add/enhance hcode_image_build and wrapper tracing for debug
- Fix CME boot to match the layout of CPMR with common scanning
- Add internal target creation to initf for testing
- Update p9_hcode_image_defines with realistic sizes.
- Cleaned up some wrappers for better debug and tracing
- Cleaned up some extraneous defines
- Fixed vector constructor functionality.
    - Removed -gc-sections from stop_gpe.mk so that constructor code remained
    - Fixed hcode_image_build in its adding of scan rings to not overlay the
      Hcode data region.
- Fix quad based creation of local target
- Redid boot_loader to properly deal with scan ring sections
- Fix boot copier header dependency
- Moved SGPE Hcode space to 38KB to deal with present size;  Made SGPE total
  OCC SRAM allocation 80KB for now.  This growth is due to fapi2 required
  vector support (4 x 128KB) plus target init (1KB) plus scan ring allocation
  per latest assumptions. The FAPI2 elements will be readdressed later.
- Remove skip arrayinit/scan0 from istep15_hack and into EPM_TUNING
- Some bug fixes in hcode_image_defines to get proper common ring offsets
  in SGPE header as well as proper placement of common rings in image
- Changes from Prasad with putrings updates
- Removed break points to call broadside scans in CME and SGPE codes.
- Added Prasad's changes for putring for CME and SGPE.
- Increased thread stack size
- Rebased and commented out memory faulting code for now
- Removed call in p9_pm_stop_gpe_init to ppe_state due to HB strings (for now)
- Fix SGPE_ALLOCATED_SIZE
- Boot loader fix
- Pulled in PK PBA context bug fix as this corrupts the PBASLVCTL0 and thus
  memory accesses
- Make CPMR and CME Header values have maximums. Add check to not allow overrun
- Hcode Image Wrapper update
- CME header debug output
