Subject: [PATCH 1/2] dt-bindings: clocks: qcom,gcc-ipq8074: allow QMP PCI PHY PIPE clocks

Allow passing QMP PCI PHY PIPE clocks to the IPQ8074 GCC to avoid having
to do a global matching by name.

Subject: [PATCH 2/2] arm64: dts: qcom: ipq8074: pass QMP PCI PHY PIPE clocks to GCC

Pass QMP PCI PHY PIPE clocks to the GCC controller so it does not have to
find them by matching globaly by name.

If not passed directly, driver maintains backwards compatibility by then
falling back to global lookup.
