Subject: [PATCH] ASoC: mediatek: mt8186: Remove unused mt8186_afe_(suspend|resume)_clock

From: "Dr. David Alan Gilbert" <linux@...blig.org>

mt8186_afe_resume_clock() and mt8186_afe_suspend_clock() were
added in 2022 by
commit 55b423d5623c ("ASoC: mediatek: mt8186: support audio clock control
in platform driver")

but have remained unused.

Remove them.
