ipq8064: Make timer code compile

Commment out nonessential timer services and modify the source code to
cleanly build in coeboot environment. Do not remove dead code just
yet, these functions might be necessary later.

Need to rename the soc timer.h to prevent collisions with timer.h in
the top level include directory.

Currently build timer code for ramstage only.

BUG=chrome-os-partner:27784
TEST='emerge-storm coreboot' still succeeds
