Commit e810dcbc (ATTN: Set up attention area to handle attention) broke
tests, as the familiy of CPU_TO_BEXX macros are not compile time constant.
hdata/test/../spira.c:60:4: error: initializer element is not constant
.addr = CPU_TO_BE64((unsigned long)&(cpu_ctl_spat_area) + SKIBOOT_BASE)
There is no test coverage of this code, so for now we can comment out
these areas in order to allow the tests to pass.

We are missing a prlog for tests. This adds a dumb version that ignores
the log level and uses printf to display all messages.

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

- Better function naming
- Better macro naming
- Re-ordered function variables
- calculate max_mdst_entry after allocating memory
for mdst table.
No change in functionality.
