Rewrite: - use pseudo-dma - provide the same features and interface as sio - support multiple boards - fix bugs. Some compile-time configuration constants are set to support higher speeds and Cyclom-16Y's at a 30% relative cost in efficiency. Cyclom-16Y support is untested.

/*
* Definitions for Cyclades Cyclom-Y serial boards.
*/
Untangled the Cyclades offsets a little. CY16_RESET and CY_CLEAR_INTR were half of their physical offsets for ISA and 1/4 of their physical offsets for PCI, while all other Cyclades offsets were physical/1 for ISA and physical/2 for PCI. Logically wrong macros were used to scale CY16_RESET and CY_CLEAR_INTR to the correct physical offsets. Fixed some style bugs (mostly long lines).

Implemented a more sophisticated mechanism for finding the chip iobase so that 32Y boards will work. Fixed bogus indenting and added a pair of parens.

Cleaned up previous commit, mainly by moving repetitive calculations of invariants to cyattach(). Fixed minor bugs: - cyparam() returned without restoring the ipl in the error cases. This was harmless because cyparam() is always called at spltty(). - one check for "rev. J or higher" actually checked for precisely rev. J.
