we need to cleanup all the variables  once we get the distro config
included in anyways... I had decided not to rock the apple cart too much
with this patch -> just the basic consolidation with as minimal changes
as necessary. inclusion of DEFAULT_LINUX_BOOT_ENV into keystone2.h can
be done as a follow on patch.

after the series: http://pastebin.ubuntu.com/11893531/
before the series: http://pastebin.ubuntu.com/11893576/
deltas:
bootdelay is 1 now
additional definitions:
arch=arm
soc=keystone    	
vendor=ti
cpu=armv7
board=ks2_evm
board_name=ks2_evm

will be great to get a tested by on that. Nothing else seems to have
changed.

arm_v7_common defines just "u-boot#" for all SoC and boards. So, we dont
need this.

Thanks.. will drop.

for i in `git grep "^#define" include/configs/ti_armv7_keystone2.h|sed
-e "s/\s\s*/ /g"|cut -d ' ' -f2|sort|uniq`; do k=`git grep $i
include/configs/ti_armv7_common.h`; if [ -n "$k" ]; then echo $i; fi; done

Then started cleaning them up.
