sound updates for 4.18

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

ASoC: Updates for v4.18

This is a very big update, mainly due to a huge set of new drivers some
of which are individually very large.  We also have a lot of fixes for
the topology stuff, several of the users have stepped up and fixed some
the serious issues there, and continued progress on the transition away
from CODEC specific drivers to generic component drivers.

 - Many fixes for the topology code, including fixes for the half done
   v4 ABI compatibility from Guenter Roeck and other ABI fixes from
   Kirill Marinushkin.
 - Lots of cleanup for Intel platforms based on Realtek CODECs from Hans
   de Goode.
 - More followups on removing legacy CODEC things and transitioning to
   components from Morimoto-san.
 - Conversion of OMAP DMA to the new, more standard SDMA-PCM driver.
 - A series of fixes and updates to the rather elderly Cirrus Logic SoC
   drivers from Alexander Sverdlin.
 - Qualcomm DSP support from Srinivas Kandagatla.
 - New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek
   MT6351, MT6797 and MT7622, Qualcomm DSPs, Realtek RT1305, RT1306 and
   RT5668 and TI TSCS454
