This syncs the phy interface modes with Linux and adds names
that were previously missing. With this we no longer have holes in
the phy mode name arrays and thus of_get_phy_mode no longer
derefences NULL pointers when it finds such a hole.

iterate over the different property names rather than having
the same code three times.

net: phy: add minimal support for QSGMII PHY
This commit adds the necessary definitions for the PHY layer to
recognize "qsgmii" as a valid PHY interface. A QSMII interface, as
defined at
http://en.wikipedia.org/wiki/Media_Independent_Interface#Quad_Serial_Gigabit_Media_Independent_Interface,
is "is a method of combining four SGMII lines into a 5Gbit/s
interface. QSGMII, like SGMII, uses LVDS signalling for the TX and RX
data and a single LVDS clock signal. QSGMII uses significantly fewer
signal lines than four SGMII busses."
This type of MAC <-> PHY connection might require special handling on
the MAC driver side, so it should be possible to express this type of
MAC <-> PHY connection, for example in the Device Tree.

ePAPR defines phy-connection-type as standard property for PHY interface
between Ethernet device and PHY device. Add corresponding property check
to of_get_phy_mode.

To start synchronizing OF API of barebox with linux OF API, this adds
a length pointer to of_find_property. Also all current users of that
function are updated to reflect the API change.
