Subject: [PATCH v5] arm64: dts: qcom: sc7280: Add lpasscore & lpassaudio clock controllers

Add the low pass audio clock controller device nodes. Keep the lpasscc
clock node disabled and enabled for lpass pil based devices.

Signed-off-by: Taniya Das <quic_tdas@...cinc.com>

[v5]
 * Update the lpasscore phandle as 'lpass_core' for consistency.

[v4]
 * Mark lpasscc[lpasscc@...0000] device node as "disabled".

[v3]
 * Fix unwanted extra spaces in reg property.
 * Fix lpass_aon node clock phandle <&lpasscc> to <&lpasscore>
