Limit the rate of h/w watch-dog triggering on the LWMON5 board by the CONFIG_WD_MAX_RATE value. Note that an earlier version of this patch which used microseconds instead of ticks dis not work. The problem was that we used usec2ticks() to convert microseconds into ticks. usec2ticks() uses get_tbclk(), which in turn calls get_sys_info(). It turns out that this function does a lot of prolonged operations (like divisions) which take too much time so we do not trigger the watchdog in time, and it resets the system.
