Commit 0b50dc4fc971 ("Convert smsc911x to use ACPI as well as DT") makes
the call to smsc911x_probe_config() unconditional, and no longer fails if
there is no device node. device_get_phy_mode() is called unconditionally,
and if there is no phy node configured returns an error code. This error
code is assigned to phy_interface, and interpreted elsewhere in the code
as valid phy mode. This in turn causes qemu to crash when running a
variant of realview_pb_defconfig.

Thanks for catching that! I have a couple other minor cleanups per the reviewers.
