Currently, init process polls pipe_fd every 5s. This hurts power on battery
driven devices. Becasue this timer interrupt prevent the system from sleeping
for longer time. This patch adds the polling interval to 60s. This patch does
not cause any harm to check_init_fifo() , becasue init process can make
response immediately when there is message in the pipe.
