Yin Fengwei 76662a634f loader: Update the memory address of GUEST_CFG_OFFSET
GUEST_CFG_OFFSET is used to pass the memory top info from DM

guest use it for other purpose.

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.

Yin Fengwei 223efeb986 DM: Update the default e820 table to reserve 0xF0000~0x100000
The region of MPtable/ACPI table/SMBios resides in
0xF0000 ~ 0x100000. They should be marked as RESERVED instead of
RAM type in e820 table.

Yin Fengwei 1e13533ec0 DM: Enable vsbl boot path.
There are two things here:
1. Enable basic vsbl boot functionality.
2. add long option to DM to specific vsbl file. So DM could
   choice to boot guest with vsbl.

It's hard to find a suitable short option. So only long option
is supported for vsbl file name option.

If long option "--vsbl='vsbl_file_name'" is given in DM
commandline, the "vsbl_file_name" will be loaded by DM
first and running. vsbl will be response to lead guest to
next boot stage.
