[PATCH 015/104] ASoC: wm8960: Fix PLL register writes

[Luis Henriques]

3.5.7.22 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mike Dyer <mike.dyer@xxxxxxxxxxxxx>

commit 85fa532b6ef920b32598df86b194571a7059a77c upstream.

Bit 9 of PLL2,3 and 4 is reserved as '0'. The 24bit fractional part
should be split across each register in 8bit chunks.
