ASoC: Updates  for v3.14

Not a lot going on framework wise, partly due to Christmas at least in
the case of the work I've been doing, but there's been quite a lot of
cleanup activity going on and the usual trickle of new drivers:

 - Update to the generic DMA code to support deferred probe and managed
   resources.
 - New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
   and Analog Devices AXI I2S and S/PDIF controller IPs.
 - Device tree support for the simple card, max98090 and cs42l52.
 - Conversion of the Samsung drivers to native dmaengine, making them
   multiplatform compatible and hopefully helping keep them more modern
   and up to date.
 - More regmap conversions, including a very welcome one for twl6040
   from Peter Ujfalusi.
 - A big overhaul of the DaVinci drivers also from Peter Ujfalusi.
