drm/rockchip: inno_hdmi: Move infoframe disable to separate function

The code to upload infoframes to the controller uses a weird construct
which, based on the previous function call return code, will either
disable or enable that infoframe.

In order to get rid of that argument, let's split the function to
disable the infoframe into a separate function and make it obvious what
we are doing in the error path.
