Timur Tabi 0534951ba4 ASoC: wm8960: remove 'dres' field from platform data structure
The 'dres' field (discharge resistance for headphone outputs) is no longer
used in the driver, so remove it.

It was used in the original version of the driver when entering standby
from off, but we stopped using it when we switched from having a single
startup sequence to having separate cap and capless sequences.

Mark Brown 3706163140 ASoC: wm8960: Support shared LRCLK
If the LRCLK is shared and the WM8960 is clock master then we should
enable the LRCM bit to tell the device that it should drive LRCLK when
either ADC or DAC is enabled rather than separately driving the two
LRCLKs.

Mark Brown 913d7b4cc0 ASoC: Add support for WM8960 capless mode
The WM8960 headphone outputs can be run in capless mode with OUT3
used to drive a pseudo ground for the headphone drivers. In this
mode the mono mixer is not used, the mixer should be turned on
in concert with the headphone output drivers and the device bias
levels are managed differently.

Also tweak the existing bias management to remove the use of active
discharge while we're at it since that's often audible.

Mark Brown b6877a477d ASoC: Move WM8960 platform data into include/sound
Avoids machine files having to peer into sound/soc which is a bit
rude and icky.
