This converts the GPIO-based I2C-driver to using GPIO
descriptors instead of the old global numberspace-based
GPIO interface. We:

- Convert the driver to unconditionally grab two GPIOs
  from the device by index 0 (SDA) and 1 (SCL) which
  will work fine with device tree and descriptor tables.
  The existing device trees will continue to work just
  like before, but without any roundtrip through the
  global numberspace.

FYI, I recently posted a series to deprecate (at least for DT) this error
prone indexing, in favor of using named GPIOs:

    [PATCH/RFC 0/3] i2c: gpio: Add support for named gpios in DT
    http://www.spinics.net/lists/devicetree/msg191936.html

Nice.

If Wolfram likes this series, I volunteer to rebase your patch
(oh well rewrite patch 2 from scratch, haha) on top of it as well
so he can apply the whole thing.

They will need some adjustments, I volunteer to do them.
Will provide feedback in the patches.

Yours.
