We grab a version from git tags (or SKIBOOT_VERSION environment variable),
optionally tack on EXTRA_VERSION (if from git) as well as add things to the
git version number if we're ahead of the most recent tag or the tree is dirty.
Also fix-up makefiles so that we don't have to rebuild version.c every time
you run make.
fsp attn area needed updating as we can have >40 character version strings.
We also export the version string via device tree rather than just the gitid.
For buildroot builds, setting SKIBOOT_VERSION environment variable to the
tag you grab will do the correct thing.

For better debugability, the patch adds git version and backtrace
details to user data section (along with file info which was already
present).
After adding required details TermImmedData looks like:

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
