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.

0xF0000 ~ 0x100000. They should be marked as RESERVED instead of
RAM type in e820 table.
