ASoC: Updates for 3.6

This has been a pretty quiet release - very little activity in framework
terms, mostly just a few new drivers and updates:

- Added the ability to add and remove DAPM paths dynamically, mostly for
  reparenting on clock changes.
- New machine drivers for Marvell Brownstone, ST-Ericsson Ux500
  reference platform and ttc-dkp.
- New CPU drivers for Blackfin BF6xx SPORTs in I2S mode, Marvell MMP,
  Synopsis Designware I2S controllers, and SPEAr DMA and S/PDIF
- New CODEC drivers for Dialog DA732x, ST STA529, ST-Ericsson AB8500, TI
  Isabelle and Wolfson Microelectronics WM5102 and WM5110
