Revert "endian: #define __BYTE_ORDER"
This reverts commit b3b77c8caef1750ebeea1054e39e358550ea9f55, which was
also totally broken (see commit 0d2daf5cc858 that reverted the crc32
version of it). As reported by Stephen Rothwell, it causes problems on
big-endian machines:

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.
