drm/bridge: dw-hdmi: Remove unused hdmi_enable_overflow_interrupts()
The cable_plugin member never receives an assignment, so it is always false, which causes hdmi_enable_overflow_interrupts() to never be called as per the logic below: if (hdmi->cable_plugin && hdmi->sink_is_hdmi) hdmi_enable_overflow_interrupts(hdmi); This has been the case since the driver was originally introduced in commit 9aaf880e ("imx-drm: Add mx6 hdmi transmitter support"). Remove the cable_plugin element and the hdmi_enable_overflow_interrupts() function that is never called.
