net: wireless: bcmdhd: fixed power consumption issue of P2P.

	solution : add wake_lock not to go to suspend during removing P2P GO
	interface in wl_cfg80211.c.
	Description of this issue :
	if device goes to suspend during removing the interface,
	we will fail to remove P2P GO virtual
	interface(p2p-p2p0-0).
	This will causes P2P GO still alive in firmware

net: wireless: bcmdhd: Fixed a problem of buganizer issue (11190960)

	Problem : if PNO scan occurs in Driver after p2p scan,
		  we failed to do PNO scan
	Root cause : In the wl_run_escan function, we still goes into
	p2p scan code even though current scan is PNO which is kind of
	legacy scan.

	Solution : we need to clear the staus of P2P scan before doing
	PNO SCAN.

net: wireless: bcmdhd: cancel current PNO if connection will happen

	Issue : Manta: Lack of WLS causes PNO problem
	Problem : we found that race condition happens
		between connection and PNO sometimes.
		Connection is failed due to this race condition.
	Solution: we need to cancel PNO explicitly if the connection
	request start in DHD driver.

net: wireless: bcmdhd: Change DTIM skip policy in suspend

	issue : WiFi continuously disconnects
	Root cause :
	Sometimes we got link down event due to beacon
	lost when device goes to suspend.
	This problem sometimes happens in case that DTIM is 3 and beacon
	100ms because we wake up on 900ms (100ms * 3 * 3) during
	suspend.
	This value(900ms) is too big to STA for sync up with AP time.
	This causes STA out of sync for time with the AP.
	Eventually STA got lost of beacon during long time (4secs).

	Solution :
	If the total dtim skip interval (beacon_interval *
	DTIM * 3) is greater than 300ms, we will not extend DTIM to DTIM
	* 3.
	Instead of that, we will use original value (DTIM) for wake up
	in suspend.
	Bug : 1343127 WiFi continuously disconnects
