[PATCH v2] ASoC: qcom: sc8280xp: configure codec sysclk for QCS615

Continuous high-amplitude noise could occur in the DA7213 microphone
capture path after a Bluetooth out-of-range/reset event followed by
reconnection. The noise was present in both the raw ALSA capture and
PipeWire input, confirming that it originated before Bluetooth
encoding.

The codec already obtains and enables MCLK through its DT clock and
bias-level handling. However, the machine driver did not explicitly
configure the codec sysclk during hw_params(). Enable
codec_sysclk_set for QCS615 so that the DA7213 clock source and rate
are configured before the codec power-up sequence.

Verified on QCS615 Talos with repeated Bluetooth disconnect and
reconnect cycles. The noise was no longer reproducible.

v2:
 - Drop the dependency note as the prerequisite changes are already present.
 - Rebase onto current code and regenerate the patch.
