Yin Fengwei d3a640da92 DM: add add_e820_entry to update e820 table. 
For vSBL boot path, we need to mark the memory vSBL is using
as reserved in e820 table. The add_e820_entry is added to
update the e820 table dynamically.

To simplify the code logic, we assume:
  - vSBL is put the middle of one entry of default e820 table
  - That entry has orignal RAM type in e820 table
  - The e820 table has enough space to hold two more new entries.

If there is more complicated case in the future, we could extend
add_e820_entry to handle it.

ACRN Device Model
#################

Introduction
============
The ACRN Device Model provides **device sharing** capabilities between the Service OS and Guest OSs. It is a component that is used in conjunction with the `ACRN Hypervisor`_ and this is installed within the Service OS. You can find out more about Project ACRN on the `Project ACRN documentation`_ website.
