Add support for the Extron DA HD 4K Plus series of 4K HDMI
Distrubution Amplifiers (aka HDMI Splitters).
These devices support CEC and this driver adds support for the
CEC protocol for both the input and all outputs (2, 4 or 6 outputs,
depending on the model).
It also exports the EDID from the outputs and allows reading and
setting the EDID of the input.

As reported by Randy:
WARNING: unmet direct dependencies detected for USB
Depends on [n]: USB_SUPPORT [=n] && USB_ARCH_HAS_HCD [=n]
Selected by [m]:
- USB_RAINSHADOW_CEC [=m] && MEDIA_CEC_SUPPORT [=y]
WARNING: unmet direct dependencies detected for USB_ACM
Depends on [n]: USB_SUPPORT [=n] && USB [=m] && TTY [=n]
Selected by [m]:
- USB_RAINSHADOW_CEC [=m] && MEDIA_CEC_SUPPORT [=y]
in order to be able to select USB_ACM, we need both USB_SUPPORT
and TTY. So, depends on those two.

As CEC support doesn't depend on MEDIA_SUPPORT, let's
place the platform drivers outside the media menu.
As a side effect, instead of depends on USB, drivers
just select it.
