Currently not all DAPM widget IO ops are holding their component mutex (codec or platform). Make sure this is now held for DAPM widget IO operations.

This patch breaks the P1022DS, which uses the WM8776 as a codec. The MPC8610HPCD, which is identical to the P1022DS but uses the CS4270 codec instead, works fine.

I'm guessing it's some kind of deadlock, because as soon as I start playback, the system halts. Not even Ctrl-C works.
