arm64: ensure vital sections aren't garbage collected
The driver structures live in special sections which have no direct reference to the symbols. Therefore, when garbage collecting sections in the linker the drivers are tossed out resulting in no drivers being linked into ramstage. Fix this by adding the KEEP() directive to those special sections. BUG=chrome-os-partner:29923 BRANCH=None TEST=Built and noted console starts working in ramstage.
