support IO reconfig loop for OBUS DL link training failures
- p9c DD1.1+ only, DD1.0 not supported
- FW to trigger reconfig loop back to step 0 from
sys_proc_fab_iovalid if:
1) sys_proc_fab_iovalid rc = FAPI2_RC_SUCCESS
-- AND --
2) new output o_obus_dl_rcs (vector of P9_FAB_IOVALID_DL_NOT_TRAINED_ERR rc
objects identifying links which failed on this chip) has entries
- attribute changes:
ATTR_LINK_TRAIN -- remove platinit tag, attr should init to zero (both even
and odd), and reconfig loop will adjust value as we go
