Log Message:
remove the COM_MPLOCK option.  always include the spinlock in the softc
and always call the simple_* locking functions.  the locking functions
are compiled out if they are not needed anyway, so a separate option
for this doesn't gain anything.

this also fixes the serial console on my alpha ES40 (which doesn't make much
sense since the com driver should still be under the big lock on alpha,
but whatever).
