This is the final patch to enable the msm800sev to build. This patch

adds a symbol to the model_lx/cache_as_ram.inc, and modifies some
files in the mainboard directory. This patch has been tested but there
is a remaining problem which I am tracking down. Expect one more patch
to "get it all working".
