The document was sent in [1] and merged to ASoC for-next branch as
commit 1afc60e00de3 ("dt-bindings: mediatek: mt8192: add audio afe
document").

However, [2] revealed that the commit 1afc60e00de3 breaks
dt_binding_check in linux-next due to dt-bindings/clock/mt8192-clk.h
doesn't exist.

[3] reverted the commit 1afc60e00de3 and merged as commit
7d94ca3c8acd ("ASoC: mt8192: revert add audio afe document").

dt-bindings/clock/mt8192-clk.h now can be found in linux-next per [4],
re-adds the document back.
