[PATCH 2/5] arm64: dts: qcom: purwa: Override Iris clocks and operating points

[Wangao Wang]

The Iris block on X1P differs from SM8550/X1E in its clock configuration
and requires a dedicated OPP table. The node inherited from the X1E cannot
be reused directly, and the fallback compatible "qcom,sm8550-iris" cannot
be applied.

Override the inherited clocks, clock-names, and operating points, and
replaces them with the X1P42100-specific definitions. A new OPP table
is provided to support the correct performance levels on this platform.
