This patch introduces the module_pnp_driver macro which is a
convenience macro for PNP driver modules similar to module_pci_driver.
It is intended to be used by drivers which init/exit section does nothing
but register/unregister the PNP driver. By using this macro it is
possible to eliminate a few lines of boilerplate code per PNP driver.
Based on work done by Lars-Peter Clausen <l...@metafoo.de> for other
busses (i2c and spi) and Greg KH for PCI.
