Subject: PCI: tegra194: Fix host initialization during resume
From: Vidya Sagar <vidyas@xxxxxxxxxx>
commit c4bf1f25c6c187864681d5ad4dd1fa92f62d5d32 upstream.
Commit 275e88b06a27 ("PCI: tegra: Fix host link initialization") broke
host initialization during resume as it misses out calling the API
dw_pcie_setup_rc() which is required for host and MSI initialization.
