Subject: [PATCH 14/14] arm64: dts: qcom: sa8775p: Drop PCIE_AUX_CLK from
 pcie_phy nodes

PCIe PHY hw doesn't require PCIE_AUX_CLK for functioning. This clock is
only required by the PCIe controller. Hence drop it from pcie_phy nodes.

While at it, let's also rename "phy_aux" clock to "aux" clock and move it
to first entry to maintain uniformity with other SoCs.
