    i2c: Replace the i2c API.
    
    The new API is in use in depthcharge and is based around the "i2c_transfer"
    function instead of i2c_read and i2c_write. The new function takes an array of
    i2c_seg structures which represent each portion of the transfer after a start
    bit and before the stop bit. If there's more than one segment, they're
    seperated by repeated starts.
    
    Some wrapper functions have also been added which make certain common
    operations easy. These include reading or writing a byte from a register or
    reading or writing a blob of raw data. The i2c device drivers generally use
    these wrappers but can call the i2c_transfer function directly if the need
    something different.
    
    The tegra i2c driver was very similar to the one in depthcharge and was simple
    to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and
    replace the ones in coreboot. The Exynos 5420 driver was ported from the high
    speed portion of the one in coreboot and was straightforward to port back. The
    low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot
    and were replaced with the depthcharge implementation.
