[PATCH v3 4/4] PCI: tegra194: Add PCI_ENDPOINT dependency

[Manikanta Maddireddy <mmaddireddy@nvidia.com>]

The PERST# assertion handler now calls pci_epc_linkdown() to notify
Endpoint functions before powering down the controller. This function
is only declared when CONFIG_PCI_ENDPOINT is enabled and has no stub
when endpoint support is disabled.

Add a PCI_ENDPOINT dependency to ensure that the endpoint framework is
available whenever the Tegra194 PCIe driver is built.
