[ALSA] sound/isa: kill pnp_resource_change

This removes the pnp_resource_change use from the ALSA ISAPnP drivers. In
2.4 these were useful in providing an easy path to setting the resources,
but in 2.6 they retain function as a layering violation only.
This makes for a nice cleanup (-550 lines) of ALSA but moreover, ALSA is the
only remaining user of pnp_init_resource_table(), pnp_resource_change() and
pnp_manual_config_dev() (and, in fact, of 'struct pnp_resource_table') in
the tree outide of drivers/pnp itself meaning it makes for more cleanup
potential inside the PnP layer.
Thomas Renninger acked their removal from that side, you did from the ALSA
side (CC list just copied from that thread).
Against current alsa-kernel HG. Many more potential cleanups in there, but
this _only_ removes the pnp_resource_change code. Compile tested against
current alsa-kernel HG and compile- and use-tested against 2.6.23.x (few
offsets).
