Subject: [PATCH 11/14] PCI: tegra: make it explicitly non-modular

The Kconfig currently controlling compilation of this code is:

drivers/pci/host/Kconfig:config PCI_TEGRA
drivers/pci/host/Kconfig:       bool "NVIDIA Tegra PCIe controller"

...meaning that it currently is not being built as a module by anyone.

Lets remove the few trace uses of modular code and macros, so that
when reading the driver there is no doubt it is builtin-only.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.
