The driver is pretty generic and would fit for either
PCI Slots or endpoints connected to PCI ports, so rename
the driver and module as pci-pwrctrl-generic.

Ah, just realised that Bjorn renamed these structures and helpers in
https://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git/commit/drivers/pci/pwrctrl/slot.c?h=next&id=e40d16e6c23994b28894179b87f9747edd63062a
So this needs some adapting...
