ASoC: Updates for v4.2

Browse Source 
The big thing this release has been Liam's addition of topology support
 to the core.  We've also seen quite a bit of driver work and the
 continuation of Lars' refactoring for component support.
 
  - Support for loading ASoC topology maps from firmware, intended to be
    used to allow self-describing DSP firmware images to be built which
    can map controls added by the DSP to userspace without the kernel
    needing to know about individual DSP firmwares.
  - Lots of refactoring to avoid direct access to snd_soc_codec where
    it's not needed supporting future refactoring.
  - Big refactoring and cleanup serieses for the Wolfson ADSP and TI
    TAS2552 drivers.
  - Support for TI TAS571x power amplifiers.
  - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs.
  - Support for x86 systems with RT5650 and Qualcomm Storm.

Command filtering and pass_level
--------------------------------
TCMU supports a "pass_level" option with valid values of 0 or 1. When
the value is 0 (the default), nearly all SCSI commands received for
the device are passed through to the handler. This allows maximum
flexibility but increases the amount of code required by the handler,
to support all mandatory SCSI commands. If pass_level is set to 1,
then only IO-related commands are presented, and the rest are handled
by LIO's in-kernel command emulation. The commands presented at level
1 include all versions of:
READ
WRITE
WRITE_VERIFY
XDWRITEREAD
WRITE_SAME
COMPARE_AND_WRITE
SYNCHRONIZE_CACHE
UNMAP

Write kernel log output directly into the VGA buffer or to a serial
port.
This is useful for kernel debugging when your machine crashes very
early before the console code is initialized. For normal operation
it is not recommended because it looks ugly and doesn't cooperate
with klogd/syslogd or the X server. You should normally N here,
unless you want to debug such a crash.
