media: cec-gpio: add notifier support
Add support for cec-notifier to the cec-gpio driver.
This makes it possible to associate the CEC gpio pin with an HDMI
connector. This feature was always documented in the cec-gpio bindings:
Documentation/devicetree/bindings/media/cec-gpio.txt
But support for the hdmi-phandle property was never actually implemented in
this driver.
This patch adds support for this property.
It also fixes a few incorrect error returns in the probe() function, which
skipped the call to cec_delete_adapter().
Tested on a Raspberry Pi 3B with a modified vc4 driver.
