This is a major overhaul of the hdmi-cec driver. It's based on the initial work by @wolfgar and is compatible with his libCEC implementation. A version libCEC that takes better advantage of this driver exists and will be upstreamed once this pull request is accepted. See https://github.com/warped-rudi/libcec/tree/IMX and https://github.com/warped-rudi/libcec/tree/libcec4-imx

If there is no link we need to allow writes otherwise libcec will
block on select() in the SocketWrite() call. The write() will still
fail with EAGAIN.

MXC-CEC: Return writable for poll when no link status.
The patch introduces a problem when changing CEC parameters in Kodi.
More investigation is needed to figure out how to correctly implement
section 9.1 of the CEC spec on this hardware.
