        Enabling all the display interface options and all the display
 panels.

 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: bb95b65a
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.

This looks good to me.

Tony, want to ack this? This enables all DSS features as modules. This
should go through dss tree, as this doesn't work without a fix that is
there.
