From: Chanwoo Choi

The commit 4dc3bab8687f ("PM / devfreq: Add support delayed timer for
polling mode") supports the delayed timer but this commit missed
the adding the timer type to devfreq_summary debugfs node.
Add the timer type to devfreq_summary debugfs.

Example after adding 'timer' information to debugfs_summary debugfs node
on Odroid-XU3 board as following:
root@localhost:~# cat /sys/kernel/debug/devfreq/devfreq_summary
dev parent_dev governor timer polling_ms cur_freq_Hz min_freq_Hz max_freq_Hz
