The dual_mac mode has been preserved the same way between legacy and new
driver, and one port devices works the same as 1 dual_mac port - it's safe
to switch drivers.

So, Switch BeagleBone boards to use new cpsw switch driver. Those boards
have or 2 Ext. port wired and configured in dual_mac mode by default, or
only 1 Ext. port.

For am335x-sancloud-bbe-common.dtsi also removed duplicated davinci_mdio DT
nodes which already defined in am335x-bone-common.dtsi.

changes in v2:
 - commit message updated to indicate duplicated nodes removal in am335x-sancloud-bbe-common.dtsi
 - dropped phy-handle for cpsw port in am335x-sancloud-bbe-common.dtsi

The commit message doesn't mention anything about why these are
dropped. I guess it's to remove duplication since
am335x-bone-common.dtsi already has the necessary elements. It'd be
good to clarify this in the commit message though.

As above, it'd be good to clarify in the commit message why these
entries are removed.

Can we drop phy-handle here? It's set to the same value in
am335x-bone-common.dtsi.

The dual_mac mode has been preserved the same way between legacy and new
driver, and one port devices works the same as 1 dual_mac port - it's safe
to switch drivers.

So, Switch BeagleBone boards to use new cpsw switch driver. Those boards
have or 2 Ext. port wired and configured in dual_mac mode by default, or
only 1 Ext. port.
