This feature allows a configurable table for video BIOS POST boot up display device.

If the displays in the 'Devices Attached' column are detected, the video BIOS will boot to the display combination
given in the Primary display(VGA) column and Secondary display column.  The bit pattern for either column is as
follows:

Bit:        7          6          5          4          3             2          1              0   
           LFP2    EFP2    EFP3    CRT2    LFP       EFP    Reserved       CRT 

Using the primary and secondary display combination, CLONE mode or TWIN mode can be set. To set CLONE mode, only
one device should be selected in primary and secondary display column each. The video BIOS POST boot up will be
displayed in both the devices selected in primary and secondary display column.

In TWIN mode, two display devices can be selected in the single column (either primary or secondary). Only CRT and
LVDS can be set in TWIN mode.

Some examples:
   DB 00001001, 00000001, 00001000      ; LFP+CRT  CRT on primary, LFP on secondary
   DB 00001101, 00001001, 00000100      ; LFP+CRT  LFP+CRT on primary, EFP on secondary

Note: Primay display column cannot be left empty. VGA modes will be displayed only on devices selected in primary
          display column.
