 Version5:
        Incorporating the comments from Tony Lindgren, Kevin Hilman,
 Paul Mundt & Tomi Valkeinen to build DSS & panels as modules.
 See: https://patchwork.kernel.org/patch/281492/

 Version4:
       Remove the enabling of the display panels by default.

 Version3:
       Eliminate the separate default number of FBs for
 different architecture. Keeping default FBs as 3 as before.

 Version2:
        Enables by default NEC panel used in zoom2/3/3630sdp, instead of
 Sharp LQ043T1DG01 panel enabled in previous version of this patch.

Testing:
---------
The base used for OMAP3 testing is:
branch: master
commit: 7c23277
URL: git://gitorious.org/linux-omap-dss2/linux.git

And OMAP4 testing is on the following branch + few patches to enable DSI taal panel:
branch: lo-dss2-Feb18
commit: 67bcb5600
URL: git://dev.omapzoom.org/pub/scm/axelcx/kernel-display.git

The patch is tested on 3630zoom, 3430sdp & 4430sdp, it was not tested
on OMAP2 platform due crash seen while boot.
