Add filter_chain object
Filter chains should be completely opaque to the drivers that use it.
We fix this with this patch.
~ Make the "filter chain" a new object.
~ We can build with CONFIG_TOUCHSCREEN_FILTER=n with no problems in
a cleaner way.
~ Update s3c2410_ts.c to use the filter_chain object.
~ Cleanups.
