ASoC: SOF: sof-pci-dev: don't use the community key on APL Chromebooks

As suggested by MrChromebox, the SOF driver can be used with the SOF
firmware binary signed with the production key. This patch adds an
additional check for the ApolloLake SoC before modifying the default
firmware path.

Note that ApolloLake Chromebooks officially ship with the Skylake
driver, so to use SOF the users have to explicitly opt-in with
'options intel-dspcfg dsp_driver=3'. There is no plan to change the
default selection.
