Subject: [PATCH] arm64: dts: qcom: qcm6490-idp: Update protected clocks
 list

Certain clocks are not accessible on QCM6490-IDP board,
thus mark them as protected.

Mark few clocks as protected on IDP of QCM6490.

This patchset is separated out from the series[1] to remove dependency from
the LPASS reset.
