[amlogic-display][hdmi] Do not set Video output module power on
SetDisplayPower on HDMI mode.

Previously, the display engine SetDisplayPower() method always
sets the power status of the display engine video output module,
which triggers a display hotplug interrupt for HDMI displays.

This change works around it by adding a new method
Vout::SetFrameVisible() which doesn't turn on/off the video output
module but only replaces the frame with a fixed color (black).

On core.vim3:
Test: fx shell display-tweak panel --power off
Test: fx shell display-tweak panel --power on

On Nelson:
Test: no-op.
