[PATCH 0/2] Fix for mv643xx_eth built as module

Recently [1], mv643xx_eth was changed to make use of mvmdio. However,
this change introduces two problems when mvmdio and mv643xx_eth are
built as modules:

- mvmdio is not loaded automatically by udev
- mv643xx_eth oopses when it can't find its PHY, i.e. when mvmdio is
  not yet loaded

The first problem can be fixed easily by adding a module alias for the
respective platform device.  The proposed fix for the second problem
uses EPROBE_DEFER as suggested by Thomas Petazzoni when the driver
can't find its PHY.

These patches apply on top of Florian Fainelli's patchset. They have
been tested on Marvel Kirkwood non-DT.
