video: fbdev: constify fb_fix_screeninfo and fb_var_screeninfo structures

These structures are only used to copy into other structures, so declare
them as const.

The semantic patch that makes this change in the fb_fix_screeninfo case is
as follows (http://coccinelle.lip6.fr/).  The fb_var_screeninfo case is
analogous.
