[PATCH] drivers/pnp/: cleanups

This patch contains the following possible cleanups:
- make needlessly global code static
- #if 0 the following unused global function:
  - core.c: pnp_remove_device
- #if 0 the following unneeded EXPORT_SYMBOL's:
  - card.c: pnp_add_card
  - card.c: pnp_remove_card
  - card.c: pnp_add_card_device
  - card.c: pnp_remove_card_device
  - card.c: pnp_add_card_id
  - core.c: pnp_register_protocol
  - core.c: pnp_unregister_protocol
  - core.c: pnp_add_device
  - core.c: pnp_remove_device
  - pnpacpi/core.c: pnpacpi_protocol
  - driver.c: pnp_add_id
  - isapnp/core.c: isapnp_read_byte
  - manager.c: pnp_auto_config_dev
  - resource.c: pnp_register_dependent_option
  - resource.c: pnp_register_independent_option
  - resource.c: pnp_register_irq_resource
  - resource.c: pnp_register_dma_resource
  - resource.c: pnp_register_port_resource
  - resource.c: pnp_register_mem_resource

Note that this patch #if 0's exactly one functions and removes no
functions.  Most it does is the #if 0 of EXPORT_SYMBOL's, so if any modular
code will use any of them, re-adding will be trivial.

Modular ISAPnP might be interesting in some cases, but this is more legacy
code.  If someone would work on it to sort all the issues out (starting
with the point that most users of __ISAPNP__ will have to be fixed)
re-enabling the required EXPORT_SYMBOL's won't be hard for him.
