Revert "endian: #define __BYTE_ORDER"

Browse Source 
This reverts commit b3b77c8cae, which was
also totally broken (see commit 0d2daf5cc8 that reverted the crc32
version of it).  As reported by Stephen Rothwell, it causes problems on
big-endian machines:

> fs/jfs/endian24.h:36:101: warning: "__LITTLE_ENDIAN" is not defined

The kernel has never had that crazy "__BYTE_ORDER == __LITTLE_ENDIAN"
model.  It's not how we do things, and it isn't how we _should_ do
things.  So don't go there.
