The Kconfig currently controlling compilation of this code is:
drivers/pci/host/Kconfig:config PCIE_XILINX
drivers/pci/host/Kconfig: bool "Xilinx AXI PCIe host bridge support"
...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. This
makes xilinx_pcie_free_irq_domain orphaned so we remove it too.
We don't have to worry about disallowing a driver unbind, since this
driver already does that.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
