In a previous patch, a flag for disabling twt by a dbg-cfg
was added. This will be useful for disabling twt on specific
cores, after branch-out.
However, we'd like twt to be enabled on master.
So, enable twt on master.

What's master in this context? AP mode?

Doh, sorry! This is a totally internal-based commit message language.
I'll fix it.
"master" is the master branch, as opposed to "cores" which are stable
branches.

TWT has been disabled during stabilization and further testing of the
FW code. It is now considered stable, so TWT can be enabled in the
driver.
