sound updates for 4.20

There have been little changes in ALSA core stuff, but ASoC core still
 kept rolling for the continued restructuring.  The rest are lots of
 small driver-specific changes and some minor API updates.
 Here are highlights:
 
 General:
 - Appropriate fall-through annotations everywhere
 - Some code cleanup in memalloc code, handling non-cacahed pages more
   commonly in the helper
 - Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently
 
 Drivers:
 - More HD-audio CA0132 codec improvement for supporting other Creative
   boards
 - Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
   give move support of existing HD-audio devices with DSP
 - A few device-specific HD-audio quirks as usual
 - New quirk for RME CC devices and correction for B&W PX for USB-audio
 - FireWire: code refactoring including devres usages
 
 ASoC Core:
 - Continued componentization works; it's almost done!
 - A bunch of new for_each_foo macros
 - Cleanups and fixes in DAPM code
 
 ASoC Drivers:
 - MCLK support for several different devices, including CS42L51, STM32
   SAI, and MAX98373
 - Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
   MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
   TI PCM3060

If you are already familiar with the older ALSA ver.0.5.x API, you can
check the drivers such as ``sound/pci/es1938.c`` or
``sound/pci/maestro3.c`` which have also almost the same code-base in

General
-------
The ALSA drivers are provided in two ways.
One is the trees provided as a tarball or via cvs from the ALSA's ftp
site, and another is the 2.6 (or later) Linux kernel tree. To
synchronize both, the ALSA driver tree is split into two different
trees: alsa-kernel and alsa-driver. The former contains purely the
source code for the Linux 2.6 (or later) tree. This tree is designed
only for compilation on 2.6 or later environment. The latter,
alsa-driver, contains many subtle files for compiling ALSA drivers
outside of the Linux kernel tree, wrapper functions for older 2.2 and
2.4 kernels, to adapt the latest kernel API, and additional drivers
which are still in development or in tests. The drivers in alsa-driver
tree will be moved to alsa-kernel (and eventually to the 2.6 kernel
tree) when they are finished and confirmed to work fine.
The file tree structure of ALSA driver is depicted below. Both
alsa-kernel and alsa-driver have almost the same file structure, except
for “core” directory. It's named as “acore” in alsa-driver tree.

Suppose that you create a new PCI driver for the card “xyz”. The card
module name would be snd-xyz. The new driver is usually put into the
alsa-driver tree, ``alsa-driver/pci`` directory in the case of PCI
cards. Then the driver is evaluated, audited and tested by developers

eventually will be integrated into the Linux 2.6 tree (the directory
would be ``linux/sound/pci``).
