This will prevent the module from being unloaded. There are concerns with modules not cleaning up IRQs on unload, thus unload must be specifically disallowed. Drop the remove callback as it is unused.

Support RC initialization, reset, clock, IRQ domain, and MSI domain setup. Implement platform-specific setup and register configuration for ASPEED. And provide PCI config space read/write and INTx/MSI interrupt handling.

When CONFIG_OF is unset, of_device_get_match_data() returns NULL, so LLVM knows this indirect call has no valid destination and drops the kCFI setup before the call, triggering the objtool check that makes sure all indirect calls have kCFI setup. This driver depends on OF for probing with non-NULL data for every match so this call will never be NULL in practice. Add a hard Kconfig dependency on OF to avoid the warning.

It functions only as a root complex, with a single-lane (x1) configuration. The controller includes Type 1 configuration registers, as well as IP specific registers (called AXI registers) required for various adjustments.
