sound updates for 4.18

Browse Source 
We've got many code additions at this cycle as a result of quite a few
 new drivers.  Below are highlights:
 
 Core stuff:
 - Fix the long-standing issue with the device registration order;
   the control device is now registered at last
 - PCM locking code cleanups for RT kernels
 - Fixes for possible races in ALSA timer resolution accesses
 - TLV offset definitions in uapi
 
 ASoC:
 - Many fixes for the topology stuff, including fixes for v4 ABI
   compatibility
 - Lots of cleanups / quirks for Intel platforms based on Realtek
   CODECs
 - Continued componentization works, removing legacy CODEC stuff
 - Conversion of OMAP DMA to the new, more standard SDMA-PCM driver
 - Fixes and updates to Cirrus Logic SoC drivers
 - New Qualcomm DSP support
 - New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek
   MT6351, MT6797 and MT7622, Qualcomm DSPs, Realtek RT1305, RT1306 and
   RT5668 and TI TSCS454
 
 HD-audio:
 - Finally better support for some CA0132 boards, allowing Windows
   firmware
 - HP Spectre x360 support along with a bulk of COEF stuff
 - Blacklisting power save default some known boards reported on Fedora
 
 USB-audio:
 - Continued improvements on UAC3 support; now BADD is supported
 - Fixes / improvements for Dell WD15 dock
 - Allow DMA coherent pages for PCM buffers for ARCH, MIPS & co
 
 Others:
 - New Xen sound frontend driver support
 - Cache implementation and other improvements for FireWire DICE
 - Conversions to octal permissions in allover places

Possible values are :
1 - APR simulator
2 - PC
3 - MODEM
4 - ADSP
5 - APPS
6 - MODEM2
7 - APPS2
= APR SERVICES
Each subnode of the APR node represents service tied to this apr. The name
of the nodes are not important. The properties of these nodes are defined
by the individual bindings for the specific service
- All APR services MUST contain the following property:
- reg
Usage: required
Value type: <u32>
Definition: APR Service ID
Possible values are :
3 - DSP Core Service
4 - Audio Front End Service.
5 - Voice Stream Manager Service.

Use vmalloc() for allocations of the PCM buffers (default: yes).
For architectures with non-coherent memory like ARM or MIPS, the
mmap access may give inconsistent results with vmalloc'ed
buffers. If mmap is used on such architectures, turn off this
option, so that the DMA-coherent buffers are allocated and used
instead.
