Subject: [PATCH v9 11/11] arm64: dts: qcom: sm8550: Fix PCIe PHYs and controllers nodes
First, move the pinctrl related propeties out from SoC dtsi and into the
board dts and add blank lines before status properties in the PHY nodes
to be consistent with the rest of the nodes. Then drop the pipe clock
from the controller nodes. Rename the aggre0 and aggre1 clocks to more
generic noc_aggr, and then the cnoc_pcie_sf_axi to cnoc_sf_axi. Add the
cpu-pcie interconnects to both controller nodes. Rename the pcie1 second
reset to link_down and drop the unnecessary enable-gpios. Switch the aux
clock to GCC_PCIE_1_PHY_AUX_CLK for the pcie1 PHY and drop the aux_phy
from clock-names. Also rename the nocsr reset to phy_nocsr. With this
changes we are now in line with the SC8280XP bindings.
