Log Message:
some restructuring, more or less to get support for weird IDE controllers,
eg the Cypress ISA bridge:
-put channel mapping into the chip specific part, unify with
channel_probe() into channel_map()
-use pointer to channel data as function call argument wherever possible
instead of the channel number
-allow the "compat" channel number to differ from the per-controller
channel number - for mapping and interrupt functions
-add support for SiS5598 and Cypress 82C693 chips
Mostly done by Manuel, I only contributed to the first 2 items.
