[PATCH 2/3] platform/x86: intel_cht_int33fe: use inline reference properties

[Dmitry Torokhov]

Now that static device properties allow defining reference properties
together with all other types of properties, instead of managing them
separately, let's adjust the driver.

Heikki, I do not have this hardware, so if you could try this out
it would be really great.
