LinuxKPI: add general module_driver(), use it for module_pci_driver()

Browse source 
Factor out module_pci_driver() from 366d68f283 into a general
module_driver() so other bus attachments can also use the same kind
of macro without duplicating all the lines.

Redefine module_pci_driver() using the new general macro.

No functional changes intended.
