CONFIG_PNP_DEBUG is no longer used to turn on dev_dbg() in PNP,
since we have pnp_dbg() which can be enabled at boot-time, so
this patch removes the config option.

Note that pnp_dock_event() checks "#ifdef DEBUG". But there's
never been a clear path for enabling that via configgery. It
happened that CONFIG_PNP_DEBUG enabled it after 1bd17e63a068db6,
but that was accidental and only in 2.6.26.
