The Kconfig currently controlling compilation of this code is: drivers/pci/host/Kconfig:config PCIE_XILINX_NWL drivers/pci/host/Kconfig: bool "NWL PCIe Core" ...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 explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Several functions only used by the remove function are also deleted here. 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.
