Hello,

this the third version of a series allowing to use the switch
component of the Ocelots SoC as a network interface.

The binding used is exactly the same of the one already used by Linux.

There is also a patch adding a workaround needed on the Ocelot based
boards: indeed the pin connected to the DDR reset is part of the
switch subsystem. So we need ensure that the DDR is not reset during
the switch reset.

Changelog:
v2 -> v3:

 - Use wait_for_bit_le32() whenever it is possible instead of
   timer_get_us() (Suggested by Daniel Schwierzeck)
 - Remove ocelot_ofdata_to_platdata() and get the resources directly
   from the probe function (Suggested by Daniel Schwierzeck)
 - Use dev_remap_addr_name() to simplify the address mapping
   (Suggested by Daniel Schwierzeck)
 - Simplify the mdio initialization by only manage the internal PHY
   for now

v1 -> v2:
 - Use wait_for_bit_le32() (suggested by Stefan Roese)
 - Use debug() instead of printf() for the debug messages in
   mscc_switch_reset.
