Subject: [PATCH] fsl-ifc: fix compilation error on 42 bit VA

Need to include sched.h to fix the following compilation error
if FSL_IFC is enabled on ARM64 machine.

In file included from include/linux/mmzone.h:9:0,
                 from include/linux/gfp.h:5,
                 from include/linux/kmod.h:22,
                 from include/linux/module.h:13,
                 from drivers/memory/fsl_ifc.c:22:
drivers/memory/fsl_ifc.c: In function ‘check_nand_stat’:
include/linux/wait.h:165:35: error: ‘TASK_NORMAL’ undeclared (first use in this function)

                                   ^
drivers/memory/fsl_ifc.c:136:3: note: in expansion of macro ‘wake_up’
   wake_up(&ctrl->nand_wait);
