This driver has the following properties compared to the old driver:
1. Support for multiple interfaces.
2. Interrupt driven I/O as opposed to polling/busy waiting.
3. Support for _one_ repeated start (Sr) condition, which is enough
for most real-world applications including all SMBus transfer types.
(The hardware does not support issuing arbitrary Sr conditions on the
bus.)
testing: SoC: at91sam9g45
- BQ20Z80 battery SMBus client.
- on a 2.6.38 kernel with several i2c clients (temp-sensor,
audio-codec, touchscreen-controller, w1-bridge, io-expanders)

[wsa: squashed with the following patches from Ludovic to have some flaws
fixed:
i2c: at91: use managed resources
i2c: at91: add warning about transmission issues for some devices
i2c: at91: use an id table for SoC dependent parameters
