Currently if host enable AFC in WMI INIT CMD, target will trigger AFC
request if current country has AP SP reg rules. We have changed regdb
on specific SP to enable AFC test, to not affect other SP which shares
regdb and FW, introduce INI to control AFC enable/disable for
flexibility.
And because currently no country support AP SP reg rule per spec,
so disable AFC by default.
