media: cec-notifier: also search for HDMI devices on I2C

Browse source

Currently the cec_notifier_parse_hdmi_phandle function can only be used
if the HDMI device associated with the CEC device is a platform device.
Extend the function to cover I2C devices as well, as there do exist
some I2C HDMI devices which don't handle CEC internally and need an
external CEC adapter.

[hverkuil: add missing linux/i2c.h header]
[hverkuil: only attempt to find the i2c device if CONFIG_I2C is set]
