Add the SoC I2C controller nodes to the platform devicetree. Use a
default bus frequency of 400kHz. They are AMBA devices that are matched
on PeriphID.
Set transfer timeout to 10ms instead of Linux's default of 200ms.

its own pinconf & pinmux controller. EyeQ5 is the first platform to use
gpio-nomadik independently from pinctrl-nomadik.

temperature sensor mounted which helps test the integration.
