Log Message:
Misc minor cleanup for arc interrupt handlers:
- always enable options MIPS3_ENABLE_CLOCK_INTR and just clear the compare
  register in cpu_intr() to make CLKF_BASE() works
  properly
- prepare only possible number of cpu_inttab
- use macro for interrupt priority number passed to arc_set_intr()
  to avoid confusion
- merge arc_hardware_intr() into cpu_intr()
- check independent timer interrupt first in cpu_intr()
- tweak MIPS_SR_INT_IE before calling hardclock timer handlers so that
  spllowersoftclock(9) will be invoked properly in hardclock(9)
- reenable interrupt for timer in cpu_intr() rather than each timer handlers

okay'ed by soda.

Note the real fix is to make CLKF_BASE() check all independent
interrupt sources including jazz and isa devices.
