[PATCH] Make roc duration configurable

[Sujith Manoharan]

From: Sujith Manoharan <c_manoha at qca.qualcomm.com>

The max remain-on-channel for cfg80211/mac80211 drivers is
obtained using the NL80211_ATTR_MAX_REMAIN_ON_CHANNEL_DURATION
attribute. This patch adds a config parameter to override
the driver-provided duration, which will help certain
use-cases.
