The gpmc ranges property for NAND at CS0 was being overridden by later
includes that defined gpmc ethernet nodes, effectively breaking NAND on
these systems:

	omap-gpmc 6e000000.gpmc: /ocp/gpmc@6e000000/nand@0,0 has
	malformed 'reg' property

Instead of redefining the NAND range in every such dtsi, define all
currently used ranges in omap3-overo-base.dtsi.

The Gumstix "Tobi-Duo" expansion board [1] can be used with either
OMAP3 Overo or Overo Storm COMs.  It provides two NICs using LAN9221
chips.
It is necessary to duplicate the interface information for the
second SMSC9221 chip as discussed [2].

Some devices (SMSC9217, SMSC9218 and SMSC9221 at least) have better
timings, allowing a higher transfer speed. Create a common file
with these timings.

Performance results with iperf:

- omap-gpmc-smsc911x.dtsi => 54.9 Mbps
- omap-gpmc-smsc9221.dtsi => 92.7 Mbps
