Hans Verkuil 6b0d5d344a [media] adv7604: Replace prim_mode by mode
Changes the way the primary mode is handled:
- Remove it from platform_data since it doesn't belong there.
- Add a new mode enum for use with s_routing.
- Collapse the two HDMI modes into one HDMI mode: when setting up the
  timings manually we do not need to select HDMI_COMP mode. That's only
  needed when selecting a preset.
This patch prepares for the next step where we switch to using the presets
where available.

Hans Verkuil 54450f591c [media] adv7604: driver for the Analog Devices ADV7604 video decoder
Initial version of this driver.

The full datasheets are available from the Analog Devices website:

  http://ez.analog.com/docs/DOC-1545

Not all features of the receiver are supported by this driver for various
reasons. Most notably:

- No CEC support (the CEC API needs a lot more discussion)
- Only port A of the four HDMI input ports is implemented (our hardware only
  uses that port)
- No HDCP repeater support (we don't use that either)

And since there are some 600-odd pages of datasheet for this single device,
I'm sure that there are many more things missing, but this driver does work
well for our hardware.

Note that I am using the register addresses instead of register names: the
datasheet containing the register descriptions is organized by register
address. Using names would make the datasheet lookup very hard. An attempt
was made to try and document what is being done when registers are used
instead.
