ASoC: dt-bindings: mediatek: mt8192: re-add audio afe document

The document was merged as commit 1afc60e00d ("dt-bindings: mediatek: mt8192: add audio afe document"). However, [1] revealed that the commit 1afc60e00d breaks dt_binding_check due to dt-bindings/clock/mt8192-clk.h doesn't exist. As a temporary fix, commit 7d94ca3c8a ("ASoC: mt8192: revert add audio afe document") reverted commit 1afc60e00d. dt-bindings/clock/mt8192-clk.h is in mainline per commit f35f1a23e0 ("clk: mediatek: Add dt-bindings of MT8192 clocks"). Re-adds the document back.
