libpayload arm64: Remove dependency on coreboot tables for dma areas

Libpayload should be able to setup its own dma areas and not depend on coreboot
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
