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.

The v6 was here:
https://lore.kernel.org/all/20230202123902.3831491-13-abel.vesa@linaro.org/

Changes since v6:
 * none

Changes since v5:
 * none

Changes since v4:
 * moved here the pinctrl properties and out of dtsi file

Changes since v2:
 * none

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

Super nit: add newline for consistency.

Neither controller needs the new enable gpio?

Nope, none of the controllers need it.
