[PATCH u-boot-marvell RESEND 01/11] include/linux/byteorder: Fix compilation of __constant_cpu_to_be32()

[Marek Behún]

From: Pali Rohár <pali at kernel.org>

The macro __constant_cpu_to_be32() uses ___constant_swab32(), which for
some reason is not defined and causes the following error during
compilation:

  include/linux/byteorder/little_endian.h:28:52: warning:
    implicit declaration of function ‘___constant_swab32’;
    did you mean ‘__builtin_bswap32’? [-Wimplicit-function-declaration]
   #define __constant_cpu_to_be32(x) ((__force __be32)___constant_swab32((x)))

Declare all ___constant_swabXX() macros.
