4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexandre Belloni <alexandre.belloni@xxxxxxxxxxx>
commit 1b328a2e095a009518ebac05e937cc0fc242fede upstream.
nck() looks at the last id in an array and unfortunately,
at91sam9x35_periphck has a sentinel, hence the id is 0 and the calculated
number of peripheral clocks is 1 instead of a maximum of 31.
