Subject: [PATCH 2/4] PNP: Compile all pnp built-in stuff in one module namespace

before, dynamic debug info (/sys/kernel/debug/dynamic_debug/control) showed
the file name as module name of each dynamic debug message (in square brackets):
drivers/pnp/core.c:198 [core]pnp_add_device p "%s device, IDs%s (%s)\012"
drivers/pnp/resource.c:619 [resource]pnp_add_bus_resource p "  add %pr\012"
..
drivers/pnp/pnpacpi/core.c:89 [core]pnpacpi_set_resources p "set resources\012"
..

With this patch the module name will be pnp for all "drivers/pnp/* -r" code:
drivers/pnp/core.c:198 [pnp]pnp_add_device p "%s device, IDs%s (%s)\012"
drivers/pnp/resource.c:619 [pnp]pnp_add_bus_resource p "  add %pr\012"
..
drivers/pnp/pnpacpi/core.c:112 [pnp]pnpacpi_disable_resources p "disable resources\012"

This has advantages:
  - Any pnp code can make use of the moduleparam.h interface, the modules
    will show up as pnp.param.
  - Passing pnp.ddebug as kernel boot param will enable all pnp debug messages
    with my previous patch and CONFIG_DYNAMIC_DEBUG enabled.
