ATTN: Set up attention area to handle attention
At present CPU control area ntuple in SPIRA structure is NULL.
ATTN component in Service Processor side checks for this field and if its empty,
it logs hardcoded SRC (0xBB821410) and generates SYSDUMP. So we have 1 SRC for
all failure (assert call) from OPAL side. This makes difficult to debug the issue.
Service processor provides attention area interface (FIPS PHyp Attentions spec),
so that we can pass SRC and user data (error message) to service processor.
This will helps us identify different failures in OPAL.
This patch enables attention area and provides interface (update_sp_attn_area())
to add src and user data (error message) through assert macro.
Attention SRC format:
1st byte - Opal src type
2-4 bytes - Holds the address of the assert function call
