This series of patches adds loadable kernel module and power management
support to Tegra PCIe host controller driver. irq_set_msi_desc() and
tegra_cpuidle_pcie_irqs_in_use() symbols will be taken care in next
set of patches.

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

V2: PM QoS fix is dropped in V2 from this series because the fix is
incorporated in latest 'commit 0759e80b84e3 ("PM / QoS: Fix device resume
latency framework")'. Update commit message of few patches in V2.

V3: Patches to export irq_set_msi_desc() and tegra_cpuidle_pcie_irqs_in_use()
are dropped based on review comments. These symbols will be addressed in next
series. Took care of few other review comments.

V4: Dropped pci_find_host_bridge() export patch and added new patch to use
bus->sysdata for private data.

V5: Decouple from https://patchwork.ozlabs.org/patch/832053/ and rebase
on top of linux-next

V6: Rebased on lpieralisi/pci/tegra branch

V7: Addressed comments on patch: 6 and 7 in V6
Limiting this series to linux-tegra & linux-pci since patches for other 
subsystem are merged or dropped

With the exception of the failure when building as a module that I
mentioned on patch 3/4, I've successfully tested this on Tegra20
(TrimSlice), Tegra30 (Beaver) and Tegra186 (Jetson TX2):
