Subject: clk: Fix JSON output in debugfs

commit 7cb81136d2efe0f5ed9d965857f4756a15e6c338 upstream.

key/value pairs in a JSON object must be separated by a comma.
After adding the properties "accuracy" and "phase" the JSON output
of /sys/kernel/debug/clk/clk_dump is invalid.

So add the missing commas to fix it.
