4.9-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit f15096f12a4e9340168df5fdd9201aa8ed60d59e ]
According to bindings/regulator/fixed-regulator.txt the 'clocks' and 'clock-names' properties are not valid ones.
In order to turn on the Wifi clock the correct location for describing the CLKO2 clock is via a mmc-pwrseq handle, so do it accordingly.
