Merge branch 'pci/controller/tegra'

- Export irq_domain_free_irqs() to allow PCI/MSI drivers that tear down
  MSI domains to be built as modules (Aaron Kling)

- Export tegra_cpuidle_pcie_irqs_in_use(), which disables Tegra CC6 while
  PCI IRQs are in use, so pci-tegra can be built as a module (Aaron Kling)

- Allow pci-tegra to be built as a module (Aaron Kling)

* pci/controller/tegra:
  PCI: tegra: Allow building as a module
  cpuidle: tegra: Export tegra_cpuidle_pcie_irqs_in_use()
  irqdomain: Export irq_domain_free_irqs()
