sound updates for 4.2-rc1

Browse source 
It was a busy development cycle at this time, as you can see a wide
 range of changes in diffstat.  There are no big changes but many
 refactoring and improvements.  Here we go some highlights:
 
 * ALSA core:
 - Procfs codes were cleaned up to use seq_file
 - Procfs can be opt out via Kconfig (only for EXPERT)
 - Two types of jack API were unified finally; now both kctl and input
   jack devs are handled via a single function call.
 
 * HD-audio
 - Continued code restructuring for the future ASoC driver; now HDA
   controller driver is split to a core helper module.
 - Preliminary codes for Skylake audio support in HDA core.
 - Proper i915 gfx power well management for SKL & co
 - Enabled runtime PM as default for Intel HDMI/DP codecs
 - Newer Tegra chip supports
 - More quirks for Dell headsets, Alienware (with CA0132), etc.
 - A couple of DRM ELD helper API functions
 
 * ASoC
 - 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, cleanup and enhancement for the Wolfson ADSP driver
 - Cleanup series for TI TAS2552 and R-CAR drivers
 - Fixes and improvements on RT56xx codecs
 - Support for TI TAS571x power amplifiers
 - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs
 - Support for x86 systems with RT5650 and Qualcomm Storm
 - Support for Mediatek AFE (Audio Front End) unit
 - Other various small fixes to ASoC codec drivers
 
 * Firewire
 - Enhanced to allow non-blocking streams to use timestamp
   synchronization
 - Improve support for DM1500 and BeBoBv3
 
 * Misc
 - Cleanup of old pci API functions over all PCI sound drivers
 - Fix long-standing regression of the old powermac i2c setup
