Subject: staging: fsl-mc: include irqreturn.h as needed

Git-commit: 06ead06dde6a7ac6c54d8e5377f1039c3f44e406
Patch-mainline: v4.14-rc1
References: fate#326530,fate#326531,fate#326535,fate#326538,fate#326539

The recent reshuffling of header files left one type definition
missing in some configurations:

In file included from drivers/staging/fsl-dpaa2/ethernet/dpaa2-eth.h:39:0,
                 from drivers/staging/fsl-dpaa2/ethernet/dpaa2-ethtool.c:34:
drivers/staging/fsl-dpaa2/ethernet/../../fsl-mc/include/dpaa2-io.h:86:1: error: unknown type name 'irqreturn_t'; did you mean 'irq_count'?
 irqreturn_t dpaa2_io_irq(struct dpaa2_io *obj);

I have not bisected this to the exact patch that introduced the problem,
but the solution is obvious, we just need to include the header that
contains the type.
