arm64: dts: ti: k3-am642-evm-pcie0-ep: Add boot phase tag to "pcie0_ep"

AM64X SoC has one instance of PCIe which is PCIe0. To support PCIe boot
on AM64X SoC, PCIe0 needs to be in endpoint mode and it needs to be
functional at all stages of PCIe boot process. Thus add the
"bootph-all" boot phase tag to "pcie0_ep" device tree node.
