media: media/platform: fsl-viu.c: fix build for MICROBLAZE

[ Upstream commit 6898dd580a045341f844862ceb775144156ec1af ]

arch/microblaze/ defines out_be32() and in_be32(), so don't do that
again in the driver source.

Fixes these build warnings:

../drivers/media/platform/fsl-viu.c:36: warning: "out_be32" redefined
../arch/microblaze/include/asm/io.h:50: note: this is the location of the previous definition
../drivers/media/platform/fsl-viu.c:37: warning: "in_be32" redefined
../arch/microblaze/include/asm/io.h:53: note: this is the location of the previous definition
