amd: raminit sysinfo offset fix
The sysinfo object within the k8 ram init is used
to communicate progess/status from all the nodes in the
system. However, the code was assuming where the sysinfo
object lived in cache-as-ram. The layout of cache-as-ram
is dynamic so one needs to do the lookup of the correct
address at runtime. The way the amd code is compiled
by #include'ing .c files makes the solution a little
more complex in that some cache-as-ram support code
needed to be refactored.
