fb_fix_screeninfo and fb_var_screeninfo structures were already
const-ified by commit 40445365a43f ("video: xilinxfb: constify
fb_fix_screeninfo and fb_var_screeninfo structures") in my -next
tree (git://github.com/bzolnier/linux.git fbdev-for-next) so
I just applied xilinx_fb_default_pdata part (patch included below
for reference).

other structure.
