wcnxxd: Trace communication between wcn36xx driver and prima

The traces contains hex dumps of the following:

HAL messages, TXBDs, TX Data, RXBDs, RX Data.

Messages and BDs are prefixed with a fake 802.11 header. This allows
you to convert it all into one pcap using the following command:

cat test.txt | grep wcnxxd | perl -pe 's/.{4}(.{12}).{20}(.+)/$1 $2/' | text2pcap -q -t "%s." -l 105 - test.pcap
DO NOT SUBMIT Print names of SMD commands in debug messages

Makes it a a little easier to read the debug logs.
