Add pinctrl definitions for Actions Semiconductor S900 I2C controllers. Pinctrl definitions are only available for I2C0, I2C1, and I2C2. Enable I2C1 and I2C2 exposed on the low speed expansion connector in Bubblegum-96 board.

|

* For the lines routed to the external connectors the

|
|
* Appendix "Expansion Connector Signal Description".
|
|
*
|
|
* When the 96Boards naming of a line and the schematic name of
|
|
* the same line are in conflict, the 96Boards specification
|
|
* takes precedence, which means that the external UART on the
|
|
* LSEC is named UART0 while the schematic and SoC names this
|
|
* UART2. Only exception is the I2C lines for which the schematic
|
|
* naming has been preferred. This is only for the informational
|
|
* lines i.e. "[FOO]", the GPIO named lines "GPIO-A" thru "GPIO-L"
|
|
* are the only ones actually used for GPIO.
