wifi: iwlwifi: do not announce EPCS support
[ Upstream commit a23c0af103e184bb1252dddddda040f6641bea7b ]
mac80211 does not have proper support for EPCS currently as that would
require changing the ECDA parameters if EPCS (Emergency Preparedness
Communications Service) is in use. As such, do not announce support for
it in the capabilities.
