Subject: [PATCH v2 0/2] Add HDMI audio on the Radxa ROCK 5B

To support HDMI audio on the rk3588 based devices, the generic HDMI
Codec framework is used in the dw-hdmi-qp DRM bridge driver.

The implementation is mainly based on the downstream driver, ported to the
generic HDMI Codec framework [1] recently merged in the DRM tree.
The parameters computation has been kept as is and the data stored in the
dw_hdmi_qp struct as been cleaned up.

The downstream kernel also implements a machine driver for HDMI audio but
it is doing exactly what the simple-audio-card driver does, so use that
instead in the ROCK 5B device tree.

Based on Linus' master branch.

Changes since v1:
 - Remove useless audio_mutex (was used downstream for multiple drivers access
   to audio functions)
 - Let hdmi_codec build and setup audio infoframes
 - Only access audio registers when connector is connected
 - Rebased on master branch
