Subject: [PATCH v5 1/3] arm64: dts: qcom: sm8450: correct pcie1 phy clocks
 inputs to gcc

The PCIe Gen4x2 PHY found in the SM8450 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.

Now the pcie1_phy exposes 2 clocks, properly add the pcie1_phy provided
clocks to the Global Clock Controller (GCC) node clocks inputs.
