Chip address extension workaround for HW423589 (option2), part1

chip_ec_attributes.xml
nest_attributes.xml
p9_sbe_attributes.xml
  add ATTR_CHIP_EC_FEATURE_EXTENDED_ADDRESSING_MODE, defines
    set of chips which physically support the feature
  add ATTR_CHIP_EC_FEATURE_HW423589_OPTION2, defines set of chips
    which need extended address workaround for MCD issue (applied only
    to Nimbus EC 21)
  add ATTR_MAX_INTERLEAVE_GROUP_SIZE, to restrict maximum size of
    memory groups formed.  Written by p9_mss_eff_grouping.  For
    HW423589_OPTION2, this will default to 512GB
  add ATTR_FABRIC_ADDR_EXTENSION_[GROUP|CHIP]_ID, to hold
    extended address configuration.  Written by p9_sbe_fabricinit (SBE)
    and p9_mss_eff_grouping (HB).  For HW423589_OPTION2, this will
    default to 0b0000_111, consuming all chip ID bits for extended
    addressing.

p9_fbc_utils.C
p9_fbc_utils.H
  extend p9_fbc_utils_get_chip_base_address to support address
  extension, now outputs set of ranges in each msel based on
  ATTR_FABRIC_ADDR_EXTENSION[GROUP|CHIP]_ID

  maintain original function for PPE platform which requires
  knowledge of non-aliased base addresses only, for code size

p9_mss_eff_grouping.C
p9_mss_eff_grouping_errors.xml
  set ATTR_FABRIC_ADDR_EXTENSION[GROUP|CHIP]_ID for HB platform
  restrict size of groups formed for HW423589_OPTION2

p9_sbe_fabricinit.C
  set ATTR_FABRIC_ADDR_EXTENSION[GROUP|CHIP]_ID for SBE platform
  configure FBC/NMMU extended addressing registers

p9_setup_bars.C
p9_setup_bars_defs.H
p9_setup_bars_errors.xml
  add general purpose support for extended address mode
  for HW423589_OPTION2, configure static MCD setup

p9_hcode_image_defines.H
p9_hcode_image_build.C
  customize SGPE image with address extension configuration to apply

p9.l3.scom.initfile

p9.trace.scan.initfile
p9.vas.scom.initfile
p9_hcd_cache_scominit.C
p9_hcd_cache_scominit.c
p9_pcie_config.C
  set unit address extension configuration on supported chips

p9_rng_init_phase2.C
p9_sbe_scominit.C
p9c_set_inband_addr.C
p9_sbe_load_bootloader.C
p9_sbe_mcs_setup.C
  adapt to alterations in p9_fbc_utils_get_chip_base_address
