Subject: [PATCH 2/2] drivers/pci: make host/pci-rcar-gen2.c explicitly non-modular

The Kconfig currently controlling compilation of this code is:

drivers/pci/host/Kconfig:config PCI_RCAR_GEN2
drivers/pci/host/Kconfig:       bool "Renesas R-Car Gen2 Internal PCI controller"

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

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We don't have to disallow a driver unbind, since that is already
done for us in this driver.

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

We don't replace module.h with init.h since the file already has that.

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.
