linux-yocto-rt: 3.4.9-rt17 remaining changes

The first import of 3.4.9-rt17 only picked up part of the import due
to a merge conflict with the modified files, and then SRCREVs being
generated from the pre-merge commit.

This SRCREV update picks up the rest of the modified files for full
-rt support.
