Use non-void configurations
This patch defines a ts_filter_configuration structure to
avoid using void* in the filter initialization, fixing another
upstream correction. This also makes the initialization more readable.
Tested in GTA02/rev6.
Other changes:
~ Comment filter configuration structures.
~ ts_filter.c:ts_filter_chain_create improved.
~ Small cleanups.
~ More TODOs/FIXMEs.
~ Updated GTA02 filter configuration.
~ Updated GTA01 filter configuration.
~ Updated mach-s3c2410/include/mach/ts.h for the new ts. configuration
structure.
~ Updated all the filters to use the new configuration structure.
~ Removed MAX_TS_FILTER_CHAIN constant that is no longer needed.
No more evil casts left it seems.
