When a DC window is being released, a NULL flip is used to indicate
that the window should be disabled. To disable a window, 0 is
written to WIN_OPTIONS.
The MC_DECERR on window shutdown is a symptom of forgetting step 2)
below when disabling windows, leaving no indication that there is
anything to wait for. This causes DC to erroneously unpin the
scanout buffer while the buffer is still actively being used.
Summary of flip (window update) synchronization in DC:
1) program some window registers
2) set win->dirty=1
3) schedule the activation of the registers
4) request VBLANK or HBLANK interrupts
5) wait for win->dirty==0
In the trigger_windows ISR (every VBLANK or HBLANK):
1) if there is no window update pending in HW, clear dirty flag to
indicate that ACTIVE registers are up-to-date.

Becasue of a previous workaround, suspend/resume pair is implemented as
suspend/complete pair in the driver's dev_pm_ops field.
If any driver suspend routine (which is called before otg suspend)
failed, then tegra_otg_resume() will be called even tegra_otg_suspend()
is not called. This will cause disable the OTG clock, and OTG will not
generate any more IRQ.
Ideal fix would be use suspend/resume pair to implement the dev_pm_ops,
but this might break previous workaround. This patch check suspend()
routine is called or not in the resume routine; even we use suspend/
resume pair in the future, it will not cause bad behaviour.

- Deauth frame from p2p GO to client doesn't go from firmware
if we do del_virtual_iface immediately. Putting a delay after
sending deauth frame to allowed FW to send out deauth frame.
- IF_DEL operation was timing out due to wrong status check.
Fixed it and added few debug prints.
- Sending Provision Discovery directly to GO instead of doing
an internal scan. Also put the internal scan count to 3 to have
better timings for GO-NEG.
- Increase beacon timeout only for concurrent mode. For STA only
operation, use the default beacon timeout value (4).
- If scan abort is due to timeout, aborting the scan in FW is not
required. Moreover, as this scan_timeout call is coming in timer
interrupt context, all blocking calls such as fw scan abort will
result in kernel panic : don’t call abort in Firmware.
- Add p2p_cancel_listen routine. Fix p2p_listen_complete related
