memory: fsl_ifc: fix leak of private memory on probe failure
[ Upstream commit 8e0d09b1232d0538066c40ed4c13086faccbdff6 ]
On probe error the driver should free the memory allocated for private
structure. Fix this by using resource-managed allocation.
Fixes: a20cbdeffce2 ("powerpc/fsl: Add support for Integrated Flash Controller")
