iwlwifi: publish STBC support in HT
Not all chips support STBC so allow this to be another config parameter per chip type. If STBC is supported then publish it in the HT caps. Since 7260/7265/3160 chips support it - set the stbc support bit. Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
