I was planning to have omap4_panda_init_rev(), which would be called
just before the i2c_init().
If other drivers need to differentiate between Panda and PandaES they
can add their code there.

We can use GPIOs to get the board ID, I'm looking at those for a
followup patch.
The only issue is that the ID1 GPIO number is different between 4430,
and 4460 based Panda.
We can have similar revision handling as we have for Beagle at the end.
