This adds a pnp_get_resource() that works the same way as

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.

This changes pnp_clean_resource_table() to take a pnp_dev pointer
rather than a pnp_resource_table pointer.  This reduces the visibility
of pnp_resource_table and removes an opportunity for error in the
caller.

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.

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.

Fix 18 errors and several warnings given by checkpatch.pl:

- use of C99 // comments;

- trailing whitespace;

- 'switch' and 'case' not at the same indentation level;

- no space before the open parenthesis of the 'if' and 'switch' statements;

- space between function name and open parenthesis (though I have introduced
  such warnins in some places since the code looks prettier with the spaces);

- including <asm/io.h> instead of <linux/io.h>;

- line over 80 characters.

In addition to these changes, also do the following:

- make the arrays in sil_set_pio_mode() 'static', and make the arrays in
  sil_set_dma_mode() 'static const';

- change the string of the 'if' statements into the 'switch' statement in
  sil_pata_udma_filter();

- drop the needless '==' operators from the 'if' statements where a condition
  is a mere bit test;

- remove needless initializer for the 'tmp' variable in init_chipset_siimage();

- beautify groups of the variable initializers and assignment operators;

- add new line after variable definitions;

- remove new line between the comment and the statements it refers to;

- remove needless curly braces and parentheses;

- fix typos, capitalize acronyms, etc. in the comments...
