drm/msm/hdmi_bridge: Correct poweroff/audio cleanup order in post_disable
Turning off the power in msm_hdmi_bridge_atomic_post_disable() should
follow reverse order of powering up, not only because it is logical, but
also because msm_hdmi_audio_update() accesses registers thus block
should still be powered on.
Depending on specific timing, existing code could have accesses to MMIO
of powered off block.
