soc/amd/common: Remove AmdReadEventLog()

Parameter passing is incorrect here, it should pass
complete StdHeader instead of attempting to fill
in HeapStatus that should be treated as a field private
to AGESA, based on where it is defined in the header
files.

Furthermore the while() loop did not evaluate the
return value. Feature can be brought back at a later
date after someone verifies it actually works correctly
across different stages.
