ARM: dts: omap3-igep0020: use SMSC9221 timings

The IGEPv2 board has a SMSC LAN9221i ethernet chip and not a SMSC LAN911x connected to the GPMC. Each chip needs different timings in order to operate correctly so is wrong to include omap-gpmc-smsc911x.dtsi instead of omap-gpmc-smsc9221.dtsi.

Hi Tony,

I see no performance difference when measuring network throughput using iperf(1) but this change is the correct one nonetheless since if we later better adjust the timings it will already include the right dtsi.

Best regards,
Javier

Yes, let's fix this as wrong timings can cause memory corruption. Applying into omap-for-v3.15/fixes-v2.
