memory: fsl_ifc: fix leak of IO mapping on probe failure
[ Upstream commit 3b132ab67fc7a358fff35e808fa65d4bea452521 ]
On probe error the driver should unmap the IO memory. Smatch reports:
drivers/memory/fsl_ifc.c:298 fsl_ifc_ctrl_probe() warn: 'fsl_ifc_ctrl_dev->gregs' not released on lines: 298.
Fixes: a20cbdeffce2 ("powerpc/fsl: Add support for Integrated Flash Controller")
