MLK-24916-3: drm: bridge: synopsys: Add HBR support for gp audio
Only non_pcm, 32bit, 192kHz, 8channel streams be recognized as
HBR streams.
In order to support this feature, need to enhance the API in
dw-hdmi driver.
The test command is:
$iecset -c 4 audio off
$aplay -Dhw:4 -r 192000 -c 8 -f S32_LE out_put.spd.iec958
$iecset -c 4 audio on
