ASoC: Updates for v4.5

Browse source 
This is quite a busy release on the driver front with a lot of new
 drivers being added but comparatively quiet on the core side with only
 one big change going in and that a fairly straightforward refactoring.
 
  - Conversion of the array of DAI links to a list by Mengdong Lin,
    supporting dynamically adding and removing DAI links.
  - Some more fixes for the topology code, though it is still not final
    and ready for enabling in production.  We really need to get to the
    point where that can be done.
  - A pile of changes for Intel SkyLake drivers which hopefully deliver
    some useful initial functionality for systems with this chipset,
    though there is more work still to come.
  - New drivers for a number of Imagination Technologies IPs.
  - Lots of new features and cleanups for the Renesas drivers.
  - ANC support for WM5110.
  - New driver for Atmel class D speaker drivers.
  - New drivers for Cirrus CS47L24 and WM1831.
  - New driver for Dialog DA7128.
  - New drivers for Realtek RT5659 and RT56156.
  - New driver for Rockchip RK3036.
  - New driver for TI PC3168A

The Imagination Technologies SPDIF Input controller contains the following
controls:
name='IEC958 Capture Mask',index=0
This control returns a mask that shows which of the IEC958 status bits
can be read using the 'IEC958 Capture Default' control.
name='IEC958 Capture Default',index=0
This control returns the status bits contained within the SPDIF stream that
is being received. The 'IEC958 Capture Mask' shows which bits can be read
from this control.
name='SPDIF In Multi Frequency Acquire',index=0
name='SPDIF In Multi Frequency Acquire',index=1
name='SPDIF In Multi Frequency Acquire',index=2
name='SPDIF In Multi Frequency Acquire',index=3
This control is used to attempt acquisition of up to four different sample
rates. The active rate can be obtained by reading the 'SPDIF In Lock Frequency'
control.
When the value of this control is set to {0,0,0,0}, the rate given to hw_params
will determine the single rate the block will capture. Else, the rate given to
hw_params will be ignored, and the block will attempt capture for each of the
four sample rates set here.
If less than four rates are required, the same rate can be specified more than
once
name='SPDIF In Lock Frequency',index=0
This control returns the active capture rate, or 0 if a lock has not been
acquired
name='SPDIF In Lock TRK',index=0
This control is used to modify the locking/jitter rejection characteristics
of the block. Larger values increase the locking range, but reduce jitter
rejection.
name='SPDIF In Lock Acquire Threshold',index=0
This control is used to change the threshold at which a lock is acquired.
name='SPDIF In Lock Release Threshold',index=0
This control is used to change the threshold at which a lock is released.
