[ARM PATCH] 1559/1: updated include/asm-arm/checksum.h big-endian support

Patch from Deepak Saxena

This is an update to patch 1529/1 that cleans up the code so we don't need 
#ifdef's for little vs. big-endian systems. Tested on both systems with
various network apps (ping, ftp, tftp, ssh, telnet, NFS root, http) with no
issues.
