Add device driver and device tree bindings for a Chrontel CEC
conroller. This is an I2C device that can send and receive CEC
messages.

Changes from v5:
- Kconfig option should depend on I2C, not select
- add flag to cec adapter in order to use notifier without addr updates
  (notifier is needed to enable CEC_CAP_CONNECTOR_INFO)
- add optional dmi matching to associate adapter with hdmi port
- read phys addr if hpd is up instead of relying on pending interrupt
  in device probe

Changes from v4:
- rebase onto master (vendor-prefixes.yaml already updated)

Changes from v3:
- address devicetree comments
- revert interrupt mask/unmask in cec adapter enable
  (the driver relies on the interrupt to get the physical address)

Changes from v2:
- fix formatting errors
- mask and unmask interrupt in cec adapter enable

Changes from v1:
- fix formatpatch.pl --strict errors
- additional comments
- enable and program logical address register
- add flags to aid interpreting transmit done status
- move ch7322 out of devicetree trivial devices
