	syssrc/sys/arch/evbmips/evbmips: clock.c clockvar.h interrupt.c
	syssrc/sys/arch/evbmips/include: param.h
	syssrc/sys/arch/evbmips/malta: autoconf.c malta_intr.c

Log Message:
Make clock/time handling more accurate:
 - Use the CPU count register for more accurate microtime (from
   sbmips) and delay (based on an evbmips delay function) functions.
 - Schedule the next hardclock interrupt more accurately (from
   an sgimips patch by Rafal Boni).  Clock drift on one board is
   now ~7ppm instead of ~330ppm.
 - Purge old pmax-based mcclock code.
 - Correctly round off some clock-derived variable calculations.
XXX: Some of this code should be migrated to sys/arch/mips.
