Dell XPS 9345 does not have an M.2 card, WLAN package is soldered
directly onboard, hence I am quite sure this is similar to QCP.
To be certain, perhaps @Tudor, Laurentiu or @Bryan O'Donoghue (if  you
have it?) could confirm from schematics?

Bluetooth and WLAN definitions were missing, as at the time I only
knew the UART port being used for bluetooth, and was missing
everything else to describe it.
