SRU; justification

Impact: The current code decides based on a PCI SSID whether a given sound
hardware has a certain hw layout. This list has to be modified each time there
is a new model. In this specific case the Dell Studio 17 is not recognized
correctly.


Fix: Applying two patches from upstream: the first enables the user to override
the hw selection by specifying one of the following values as the model=
argument to the snd-hda-intel module:

- dell-m6-amic Dell desktops/laptops with analog mics
- dell-m6-dmic Dell desktops/laptops with digital mics
- dell-m6 Dell desktops/laptops with both type of mics
This allows to make new dell-m6 hw to be tested/enabled without the need for a
new module. The second patch is a simple quirk to automatically select the
right model for the Studio 17.


Testcase: see bug report.
