[PATCH] drm/sti: select CEC_CORE if CEC_NOTIFIER

[Hans Verkuil]

If the stih-cec driver is a module and the drm sti driver is built-in, then
the CEC core will be a module also, causing the CEC notifier to fail (will be
compiled as empty functions).

To prevent this select CEC_CORE if CEC_NOTIFIER is set to ensure the CEC core
is also built into the kernel.
