Ian Lepore 97247a2acf A variety of cleanups...
- Use named constants for register bits, instead of mystery numebrs
   scattered around in the code.
 - Use inline functions for bus space read/write, instead of macros
   that rely on global variables.
 - Move the timecounter struct into the softc instead of treating it
   as a global variable.  Backlink from it to the softc.
 - This leaves a pointer to the softc as the only static/global variable
   and it's now used only by DELAY().
