The user of the packet_ram_enabled was removed, but the flag itself wasn't. Clean up. Fixes: b47a72f ("drm/vc4: hdmi: Switch to HDMI connector") Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>

Audio can be triggered by the HPD handler and start up before video has been restored, calling vc4_hdmi_write_infoframe for the audio infoframe. vc4_hdmi_write_infoframe checks that the packet RAM to store the infoframes is enabled, but that is only enabled when video is enabled in vc4_hdmi_encoder_post_crtc_enable. The packet RAM enable is only a power saving thing, so move enabling/disabling to the runtime_pm hooks. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
