Subject: bus: fsl-mc: extend fsl_mc_get_endpoint() to pass interface ID
Git-commit: 27cfdadd687deca58146b415f60b23d185cb3532
Patch-mainline: v5.15-rc1
References: jsc#SLE-19033
In case of a switch DPAA2 object, the interface ID is also needed when
querying for the object endpoint. Extend fsl_mc_get_endpoint() so that
users can also pass the interface ID that are interested in.
