PNP: add pnp_possible_config() -- can a device could be configured this way?
As part of a heuristic to identify modem devices, 8250_pnp.c
checks to see whether a device can be configured at any of the
legacy COM port addresses.
This patch moves the code that traverses the PNP "possible resource
options" from 8250_pnp.c to the PNP subsystem. This encapsulation
is important because a future patch will change the implementation
of those resource options.
