This is really moot because the driver cannot be built as a module currently
because arch_setup_msi_irq() and arch_teardown_msi_irq() need to be built-in
so tegra_pcie_disable_msi() will be called only just before the machine is
shut down.
Perhaps this is something that should be addressed? Or is it just not worth
the effort?
