PCI: Add builtin_pci_driver() to avoid registration boilerplate
In f309d4443130 ("platform_device: better support builtin boilerplate
avoidance"), we introduced the builtin_driver() macro.
Here we use that support and extend it to PCI driver registration, so where
a driver is clearly non-modular and builtin-only, we can register it in a
similar fashion. Existing code that is clearly non-modular can be updated
with the simple mapping of
module_pci_driver(...) ---> builtin_pci_driver(...)
We've essentially cloned the former to make the latter, and taken out the
remove/module_exit parts since those never get used in a non-modular build
of the code.
