The Kconfig currently controlling compilation of this code is:

drivers/pci/host/Kconfig:config PCI_RCAR_GEN2_PCIE
drivers/pci/host/Kconfig:       bool "Renesas R-Car PCIe 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.

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 have to disallow a driver unbind, since that is already
done for us in this driver.

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.

Yep, thanks -- I'll check for future sends to ensure get_maintainer.pl
hasn't omitted the module author.  Looks like it may emit the module
author if they have been actively committing, but that won't work in the
authored and then largely left it alone case.

Sure I can do that and just resend the 2 renesas commits if there is no
interest in tristate conversions for them.  As for the others, I'm still
awaiting feedback on what approach people want to take;  I listed what I
figured our possible options are.
