The TFP410 driver does not support I2C. As such, the device remains in Power Down if the I2C is enabled by the bootstrap pins. Add basic support for the I2C interface, and provide support to take the device out of power down when enabled. Also read the bootstrap mode pins via the CTL_1_MODE register when using the I2C bus. Also allow polling device to support hdmi/dvi hotplug detection.
