kexec can leave MMU registers set, PIDR in particular, when booting the
new kernel. The boot sequence does not zero PIDR ever, and it only gets
changed as CPUs first switch to userspace processes. This can leave a
window where speculative accesses from a CPU to quadrant 0 can pick up
translations i

The fman driver only calls of_get_phy_node, ignoring the
phy-connection-type field. While we're at it, update the fixed link to
the new more readable way to specify it and set phy-mode to rgmii-id for
the node with a phy.

tracepoints at this stage will make kexec to fail if enabled.
