Subject: [PATCH v2 1/4] arm64: dts: qcom: sc8280xp: fix USB clock order and naming

Fix the USB controller clock order and naming so that they match the
devicetree binding.

Note that the driver currently simply enables all clocks in the order
that they are specified in the devicetree. Reordering the clocks as per
the binding means that the only explicit ordering constraint found in
the vendor driver, that cfg_noc should be enabled before the core_clk,
is now honoured.
