Subject: [PATCH AUTOSEL 4.4 04/20] mtd: rawnand: sunxi: Add an U suffix to
 NFC_PAGE_OP definition

From: Boris Brezillon <boris.brezillon@...tlin.com>

[ Upstream commit cf3e3fd2e94f4648f17fbd5e0e26409d5d1face9 ]

Fixes the "warning: large integer implicitly truncated to unsigned type
[-Woverflow]" warning when compiled for x86.

This is needed in order to allow compiling this driver when
COMPILE_TEST=y.
