Subject: [PATCH 2/2] arm64: dts: qcom: sc7280: Add a new herobrine Pro SKU

Some of the qualcomm qcard based herobrine devices can come with
a Pro variant of the chipset with some qcard level changes like
the smps9 from pm8350c which is ganged up with smps7 and smps8,
so we just end up removing smps9 from the herobrine pro sku dtsi.
We then use it to create a new dts for the Pro variant of the
herobrine CRD.
