Subject: [PATCH v5 2/3] arm64: dts: qcom: sm8550: remove pcie-1-phy-aux-clk
and add pcie1_phy pcie1_phy_aux_clk
The PCIe Gen4x2 PHY found in the SM8550 SoCs have a second clock named
"PHY_AUX_CLK" which is an input of the Global Clock Controller (GCC) which
is muxed & gated then returned to the PHY as an input.
Remove the dummy pcie-1-phy-aux-clk clock and now the pcie1_phy exposes
2 clocks, properly add the pcie1_phy provided clocks to the Global Clock
Controller (GCC) node clocks inputs.
