CHROMIUM: Fix Intel core68 build failure for amd64_generic

amd64_generic build fails due to missing mtx field in wiphy
structure. This is added in
cfg80211: avoid holding the RTNL when calling the driver
in upstream. Add support for mtx field and track backporting
above mentioned patch on previous kernel or another way to
resolve this conflict
