[RFT PATCH v2 2/2] memory: fsl_ifc: fix leak of private memory on probe failure

[Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>]

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")

Only build tested.

Changes since v1:
1. kfree() in remove() as pointed out by Dan.
