[PATCH v4 11/12] arm64: dts: qcom: sm8550: Add PCIe PHYs and controllers nodes

[Abel Vesa <abel.vesa@linaro.org>]

Add PCIe controllers and PHY nodes.

Signed-off-by: Abel Vesa <abel.vesa@linaro.org>

This patch does not have a v3, but since it is now part of the same
patchset with the controller and the phy drivers patches, I had to
bump the version to 4.

Latest version was here (v2):
https://lore.kernel.org/all/20230118230526.1499328-2-abel.vesa@linaro.org/

Changes since latest version (v2):
 * renamed the pcie_1_link_down_reset to simply link_down
 * dropped the pipe from clock-names
 * renamed aggre clock-names to noc_aggr_4
 * dropped the _pcie infix from cnoc_pcie_sf_axi
 * dropped the aux_phy clock from the pcie1

Changes since v1:
 * ordered pcie related nodes alphabetically in MTP dts
 * dropped the pipe_mux, phy_pipe and ref clocks from the pcie nodes
 * dropped the child node from the phy nodes, like Johan suggested,
   and updated to use the sc8280xp binding scheme
 * changed "pcie_1_nocsr_com_phy_reset" 2nd reset name of pcie1_phy
   to "nocsr"
 * reordered all pcie nodes properties to look similar to the ones
   from sc8280xp
