arm64: dts: ti: k3-am65: Enable PCIe nodes at the board level
PCIe nodes defined in the top-level AM65x SoC dtsi files are incomplete
and will not be functional unless they are extended with a SerDes PHY.
And usually only one of the two modes can be used at a time as they
share a SerDes link.
As the PHY and mode is only known at the board integration level, these
nodes should only be enabled when provided with this information.
Disable the PCIe nodes in the dtsi files and only enable the ones that
are actually pinned out on a given board.
