To use keep-alive mechanism in mac80211 stack, since driver supports

In order to realize the keep-alive mechanism in mac80211 stack, reporting
accurate tx ack status for nullfunc frame is added in this commit.

If current frame is nullfunc frame, we ask firmware to report by filling
TX report bit in TX descriptor. After this frame DMA done, TX interrupt is
triggered but TX status is unknown at this moment, so enqueue this skb
into tx_report->queue. Finally, C2H report will be received if the frame
is transmitted successfully or retried over, and then we report to mac80211
with IEEE80211_TX_STAT_ACK flag only if it's successful. Otherwise, if
failure or timeout (one second), we report to mac80211 without this flag.

We can have pm_runtime_get_sync() return 1, and we can have
pm_runtime_put_sync() return -EBUSY. See rpm_suspend() and
rpm_resume() for more information.

Fix the issue by returning 0 from wl12xx_sdio_power_on() on success.
And use pm_runtime_put() instead of pm_runtime_put_sync() for
wl12xx_sdio_power_off(), then the MMC subsystem will idle the bus
when suitable.

Otherwise wlcore can sometimes get confused and may report bogus
errors and WLAN connection can fail.

Note that while wlcore checks the return value for wl1271_power_on(),
the return value is ignored for wl1271_power_off(). Let's fix them
both though to avoid further confusion in the future.

It's how firmware reports support for various features, e.g. supported

Access to all that info is useful for trying new firmwares, comparing
