[PATCH 03/21] ath10k: Support setting debug mask from driver code.

[greearb at candelatech.com]

From: Ben Greear <greearb at candelatech.com>

Might want to turn off verbose debug as soon as you
see a firmware crash, for instance.  Helps keep dmesg
output from over-running the stuff you care about.
