ASoC: msm: Add hwdep node for NOIRQ FE
ALSA lacks support to accept shared memory supplied
from userspace. But some usecases need to get a shareable
file descriptor for the dma buffer. As an alternate
to adding custom ioctls to the ALSA framework, use
a hwdep node to get a file descriptor to the underlying dma buffer.
Maintain compat mode as well.
