Currently, the I2C clocks are configured in the sunxi board code. Add
the I2C clocks to the DM clock driver so they can be enabled from the
DM I2C driver using the normal uclass methods.

Add a driver so the clocks/resets for these peripherals (especially I2C,
RSB, and UART) can be enabled using the normal uclass methods.
