TI: OMAP3: Overo Tobi ethernet support

Browse Source 
Add setup for ethernet on Tobi, allowing kernel/ramdisk to be loaded
over tftp.

This also refactors the smc911x driver to allow for detecting when the
chip is missing. I.e. the detect_chip() function is called earlier and
will abort gracefully when the Chip ID read returns all 1's.
