Subject: [PATCH 4.14 41/80] Revert "microblaze: fix endian handling"

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

This reverts commit ac3d021048be9edb825f0794da5b42f04fefecef which is
commit 71e7673dadfdae0605d4c1f66ecb4b045c79fe0f upstream.

kbuild reports that this causes build regressions in 4.14.y, so drop it.
