This series of patches add loadable kernel module and power management
support to Tegra PCIe host controller driver.

These patches are tested on Jetson TK1, TX1 and TX2 platforms, following
are the verification details.
- Multiple module insert & remove
- PCIe device functionality after module insert
- Free clock, resets, regulators, powergate, iomem and interrupt
resources after module remove
- PCIe device functionality after resume from RAM

Tegra PCIe host controller driver is using ioremap_page_range() which is
not exported. This is switched with devm_ioremap() in the series
'https://patchwork.ozlabs.org/project/linux-tegra/list/?series=9907'.
Both these series will complete the loadable module support for Tegra
PCIe host driver.

Manikanta Maddireddy (10):
genirq: Export irq_set_msi_desc()
of: Export of_pci_range_to_resource()
PM / QoS: Fix device resume latency for non PM QoS devices
ARM: tegra: EXPORT tegra_cpuidle_pcie_irqs_in_use()
PCI: Export pci_find_host_bridge()
PCI: Export pci_flags
PCI: tegra: free resources on probe failure
PCI: tegra: Add loadable kernel module support
PCI: tegra: Broadcast PME_turn_Off message before link goes to L2
PCI: tegra: Add power management support
