AP: Pass station P2P PS capabilities info during station add/set

If a legacy client with no P2P PS support is trying to connect to
a P2P GO, the driver should know that, and change its PS behavior
accordingly.

Add a parameter to hostapd_sta_add_params() indicating if P2P PS is
supported by the station and pass this parameter to kernel with nl80211
driver when the station is added/set.
