PCI: tegra194: Allow system suspend when the Endpoint link is not up
Host software initiates the L2 sequence. PCIe link is kept in L2 state
during suspend. If Endpoint mode is enabled and the link is up, the
software cannot proceed with suspend. However, when the PCIe Endpoint
driver is probed, but the PCIe link is not up, Tegra can go into suspend
state. So, allow system to suspend in this case.
