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 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
