[PATCH 04/11] PCI: tegra194: Do not skip no-link Root Port remove cleanup

[Manikanta Maddireddy <mmaddireddy@nvidia.com>]

tegra_pcie_config_rp() deinitializes the controller and disables runtime PM
when link training fails, then probe treats -ENOMEDIUM as success so the
driver can remain bound without a link.

remove() returned immediately when the Root Port link was down. That skips
common cleanup such as tegra_bpmp_put() and deasserting the refclk-select
GPIO. Keep link-dependent controller teardown conditional, but always run
common remove cleanup.

Fixes: 56e15a238d92 ("PCI: tegra: Add Tegra194 PCIe support")
