On some boards the hpd pin of a hdmi connector is wired up to a gpio
pin. Since in the DRM world the tfp410 driver is responsible for
handling the connector, add support for hpd gpios in this very driver.

It would be nice to add 'hpd-gpios' property in the binding doc as well:
Documentation/devicetree/bindings/display/bridge/ti,tfp410.txt
The hpd-gpios property does *not* belong to the ti,tfp410 binding but to
the hdmi-connector one where it is already documented:
Documentation/devicetree/bindings/display/connector/hdmi-connector.txt
Unfortunatly, there is no dedicated driver for the connector in Linux;
the connector properties have to be handled by the encoder (here the
tfp410) driver. Note that this already happens for the ddc-i2c-bus property.
Cheers,
Christopher
