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

From: Alban Bedel <alban.bedel@avionic-design.de>
[ Upstream commit f1ca493b0b5e8f42d3b2dc8877860db2983f47b6 ]
The Charge Pump needs the DSP clock to work properly, without it the bypass to HP/LINEOUT is not working properly. This requirement is not mentioned in the datasheet but has been confirmed by Mark Brown from Wolfson.
