[PATCH v4 3/4] PCI: tegra: Allow building as a module

[Aaron Kling via B4 Relay <devnull+webgeek1234.gmail.com@kernel.org>]

From: Aaron Kling <webgeek1234@gmail.com>

This changes the module macro back to builtin, which does not define an
exit function. This will prevent the module from being unloaded. There
are concerns with modules not cleaning up IRQs on unload, thus this
needs specifically disallowed.
