Subject: PNP: make pnp_add_id() internal to PNP core

pnp_add_id() doesn't need to be exposed outside the PNP core, so
move the declaration to an internal header file.

Subject: PNP: add debug output to option registration

Add debug output to resource option registration functions (enabled
by CONFIG_PNP_DEBUG).  This uses dev_printk, so I had to add pnp_dev
arguments at the same time.

Subject: PNP: remove pnp_resource_table from internal get/set interfaces

When we call protocol->get() and protocol->set() methods, we currently
supply pointers to both the pnp_dev and the pnp_resource_table even
though the pnp_resource_table should always be the one associated with
the pnp_dev.

This removes the pnp_resource_table arguments to make it clear that
these methods only operate on the specified pnp_dev.

Subject: PNP: add pnp_init_resources(struct pnp_dev *) interface

Add pnp_init_resources(struct pnp_dev *) to replace
pnp_init_resource_table(), which takes a pointer to the
pnp_resource_table itself.  Passing only the pnp_dev * reduces
the possibility for error in the caller and removes the
pnp_resource_table implementation detail from the interface.

Even though pnp_init_resource_table() is exported, I did not
export pnp_init_resources() because it is used only by the PNP
core.

Subject: PNP: remove unused interfaces using pnp_resource_table

Rene Herman <rene.herman@gmail.com> recently removed the only in-tree
driver uses of:

    pnp_init_resource_table()
    pnp_manual_config_dev()
    pnp_resource_change()

in this change:

    http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=109c53f840e551d6e99ecfd8b0131a968332c89f

These are no longer used in the PNP core either, so we can just remove
them completely.

It's possible that there are out-of-tree drivers that use these
interfaces.  They should be changed to either (1) use PNP quirks
to work around broken hardware or firmware, or (2) use the sysfs
interfaces to control resource usage from userspace.

Subject: PNP: add pnp_get_resource() interface

This adds a pnp_get_resource() that works the same way as
platform_get_resource().  This will enable us to consolidate
many pnp_resource_table references in one place, which will
make it easier to make the table dynamic.

Subject: PNP: make pnp_resource_table private to PNP core

There are no remaining references to the PNP_MAX_* constants or
the pnp_resource_table structure outside of the PNP core.  Make
them private to the PNP core.
