libpayload arm64: Remove dependency on coreboot tables for dma areas

tables for passing this information. This patch and next allow libpayload to
setup dma areas while performing mmu_init

BUG=chrome-os-partner:31634
BRANCH=None
TEST=Compiles successfully and dma areas are setup properly with the mmu init patch
