[PATCH 07/20] iwlwifi: mvm: add a debug_enable op

[Luca Coelho <luca@coelho.fi>]

From: Shahar S Matityahu <shahar.s.matityahu@intel.com>

D3 debug data is disabled by default. Currently it is done by tampering
the dump mask. Add an operation that will allow this to be changed
without recompilation.
