dt-bindings: pci: tegra: Remove PLL power supplies
The XUSB pad controller, which provides access to various USB, PCI and SATA pads (or PHYs), needs to bring up the PLLs associated with these pads. In order to properly do so, it needs to control the power supplied to these PLLs. Remove the PLL power supplies from the PCIe controller because it does not need direct access to them. Instead it will only use the configured pads provided by the XUSB pad controller.
