Add a common hex array in hexdump.c so everyone can use it.
Add a common hi/lo helper to avoid the shifting masking that is
done to get the upper and lower nibbles of a byte value.
Pull the pack_hex_byte helper from kgdb as it is opencoded many
places in the tree that will be consolidated.

The AD181x and AZT230 chips don't support an IRQ-less MPU401 option but
work fine without one. This adds (priority functional) IRQ-less options
for each port option to help systems with few available IRQs.
The AD1815 quirk can't use pnp_register_irq_resource() due to doubly
penalizing the IRQ. Also, while not a practical issue due to no IRQ
option being present for the dependents, this needs to add in front, not
back.
Doesn't use pnp_register_port_resource() for symetry with above.
This does not delete the AD1815 independent option even though it should
be empty after the IRQ transfer due to AD1816 coming with an empty but
still present independent option by default.
Was tested on AD1815, AD1816 and AZT2320. The ALSA snd-ad1818a driver
also support the AZT2002 ID for MPU401 but this doesn't as I was unable to
test it.

The subsequent AD181x quirk patch would like this as part of the API.
pnp_register_dependent_option() adds to the same dependent chain the quirk is
walking which is fairly unclean. This enables a private option chain build
which it can then just add onto the end when done.

Save the ISAPNP config register index in the struct pnp_resource.
We need this because it is important to write ISAPNP configuration
back to the same registers we read it from. For example, if we
read valid regions from memory descriptors 0, 1, and 3, we'd
better write them back to the same registers, without compressing
them to descriptors 0, 1, and 2.
This was previously guaranteed by using the index into the
pnp_resource_table array as the ISAPNP config register index.
However, I am removing those fixed-size arrays, so we need to
save the ISAPNP register index elsewhere.

This patch removes a use of "idx" in pnp_check_port() and similar
functions, in preparation for replacing idx with a pointer to the
resource itself.
I split this out because it changes the behavior slightly: we used
to check for conflicts only with earlier resources, e.g., we checked
resource 2 against resources 0 and 1 but not against 3, 4, etc. Now
we will check against all resources except 2.
Since resources are assigned in ascending order, the old behavior
was probably safe, but I don't like to depend on that ordering.

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.
