ALSA: hda/ca0132: Fix DMic data rate for Alienware M17x R4
The commentary says to use various parameters, and lays out what
the mapping is... The code used a 32KHz rate when the comment
says that it needs to use a 48KHz rate. And this has been the
case since day one.
On the Alienware M17x R4, the DMic used to have exceptionally quiet
pickup and a lot of noise. Changing the data rate fixes both of
these issues.
Searching the kernel bug tracker for ca0132-related issues shows no
mention of this being an issue for other hardware, and I have no
other hardware to test with, so a quirk is used to limit the effect
to just the M17x R4.
