Re-write Decstation turbochannel autoconfiguration code to use the machine- 

independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h:
  * Change the tc autoconfiguration tables to use a struct tc_attach_args
    instead of the ad-hoc structure.
  * Change all pmax device drivers to use a `struct confargs' that's
    assignment-compatible with  sys/dev/tc/tcvar.h `struct tcdev_attach_args'.
    Devices that can be present on a TC or as ioctl asic/mainbus builtins
    use  the same `struct confargs'.
  * Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from
    an old, now-obsolete sys/arch/alpha snapshot.

  * Update the comments and debugging code in interrupt handlers to
    be consistent with the machine-independent TC support.

Other commits that overlap the same source files include: re-enabling
clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i.
