From: Shannon Zhao <shannon.zhao@linaro.org>

We will create EFI table, memory description table and some of acpi
tables and we're going to map them to kinfo->gnttab_start of Dom0.
Add placeholder for the starting address for loading in DOM0 and the
size of new added tables. Also add a placeholder to store the new
created tables.
