PM / devfreq: Fix indentaion of devfreq_summary debugfs node

The commit 66d0e79 ("Revert "PM / devfreq: Modify the device name
as devfreq(X) for sysfs"") roll back the device name from 'devfreqX'
to device name explained in DT. After applied commit 66d0e79,
the indentation of devfreq_summary debugfs node was broken.

So, fix indentaion of devfreq_summary debugfs node as following:

For example on Exynos5422-based Odroid-XU3 board,
$ cat /sys/kernel/debug/devfreq/devfreq_summary
dev                            parent_dev                     governor        polling_ms  cur_freq_Hz  min_freq_Hz  max_freq_Hz
