PNP: add CONFIG_PNP_DEBUG_MESSAGES and pnp_dbg()
This adds the core function pnp_dbg() and a new config option to enable it. The PNP core debugging messages can be enabled at boot-time with the "pnp.debug" kernel parameter.

+ Say Y here if you want the PNP layer to be able to produce debugging
+ messages if needed. The messages can be enabled at boot-time with
