It seems we should not even instantiate some devices on BBB
until the EEPROM is parsed.. So maybe something like this:

1. The problem devices are initially set with status = "disabled"
   in the dts

2. We set up drivers/*/bbb-eeprom.c that parses the board
   revision at module_init time, and then flips the selected
   devices to have status = "enabled" and populates the revision
   info based on the eeprom and SoC revision passed in pdata.
   Then those devices get their struct device created and
   probed, but at a much later time.

So rather than trying to init all that early, let's just
init them much later when we have the proper I2C driver
running?

Regards,

Tony
