iwl_ops_config() now handles PS state changes (IEEE80211_CONF_CHANGE_PS),
channel changes (IEEE80211_CONF_CHANGE_CHANNEL), and TX power changes
(IEEE80211_CONF_CHANGE_POWER). Tracks ps_enabled, current_channel, tx_power
in transport. Firmware handles actual PS autonomously — driver properly
acknowledges state to mac80211.
Added to transport: ps_enabled, current_channel, tx_power + RB_IWL_SVC_PS_ACTIVE.
Added to linux-kpi mac80211.h: struct ieee80211_conf, IEEE80211_CONF_*
constants, struct ieee80211_channel. Cross-referenced from Linux 7.1
include/net/mac80211.h lines 1824-1866.
Power save is no longer a gap — driver tracks PS state correctly.
