tcl/target: Move TI targets to ti folder

Move the ti targets to a TI folder. Since the folder is ti, we can
drop the "ti" prefix from the files themselves.

Done via the following script:

 mkdir target/ti
 FILES=`ls target/ti*.cfg target/omap*.cfg target/am335x.cfg
           target/amdm37x.cfg target/icepick.cfg target/stellaris.cfg
		   target/davinci.cfg`
 for cname in $FILES
 do
   bname=`basename $cname`
   nname=`echo $bname|sed -e "s/^ti-//g"|sed -e "s/ti_//g"`
   npath="target/ti/$nname"
   echo "$cname => $npath"
   fref=`git grep $cname .|cut -d ':' -f1|sort -u`
   sed -i -e "s&$cname&$npath&g" $fref
   git mv $cname $npath
 done
