ddi_get_lbolt() returns the value of lbolt where lbolt is an integer
that represents the number of clock ticks since the last system
reboot. This value is used as a counter or timer inside the system
kernel. The tick frequency can be determined by using
drv_usectohz(9F) which converts microseconds into clock ticks.
ddi_get_lbolt() returns the value of lbolt.
This routine can be called from any context.
