replace device/i2c.h with simpler version

The existing header was imported along with the Exynos code and left
    mostly unchanged. This is the first patch in a series intended to
    replace the imported u-boot I2C API with a much simpler and cleaner
    interface:

- We only need to expose i2c_read() and i2c_write() in our public API.
      Everything else is board/chip-dependent and should remain hidden
      away.

- i2c_read and i2c_write functions will take bus number as an arg
      and we'll eliminate i2c_get_bus and i2c_set_bus. Those are prone to
      error and end up cluttering the code since the user needs to save
      the old bus number, set the new one, do the read/write, and restore
      the old value (3 added steps to do a simple transaction).

- Stop setting default values for board-specific things like SPD
      and RTC bus numbers (as if we always have an SPD or RTC on I2C).

- Death to all the trivial inline wrappers. And in case there was any
      doubt, we really don't care about the MPC8xx. Though if we did then
      we would not pollute the public API with its idiosyncrasies.
