When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

With runtime PM tested working for wlcore with no autosuspend, we can
now enable autosuspend to cut down on enable/disable for interrupts.
Basically we just replace pm_runtime_put() with the autosuspend variants.
Let's use autosuspend delay of 50ms that MMC drivers typically use.

We can update wlcore to use PM runtime by adding functions for
wlcore_runtime_suspend() and wlcore_runtime_resume() and replacing
calls to wl1271_ps_elp_wakeup() and wl1271_ps_elp_sleep() with calls
to pm_runtime_get_sync() and pm_runtime_put().
Note that the new wlcore_runtime_suspend() and wlcore_runtime_resume()
functions are based on simplified versions of wl1271_ps_elp_sleep() and
wl1271_ps_elp_wakeup().
We don't want to use the old functions as we can now take advantage of
the runtime PM usage count. And we don't need the old elp_work at all.
And we can also remove WL1271_FLAG_ELP_REQUESTED that is no longer needed.
Pretty much the only place where we are not just converting the existing
functions is wl1271_op_suspend() where we add pm_runtime_put_noidle()
to keep the calls paired.
As the next step is to implement runtime PM autosuspend, let's not add
wrapper functions for the generic runtime PM calls. We would be getting
rid of any wrapper functions anyways.
After autoidle we should be able to start using Linux generic wakeirqs
for the padconf interrupt.

Add debugfs key (under CFG80211_CERTIFICATION_ONUS
configuration) to set/clear radar_debug_mode.
In this mode, the driver simply ignores radar
events (but prints them).
The fw is notified about this mode through
a special generic_cfg_feature command.
This mode is relevant only for ap mode. look for
it when initializing ap vif.

In struct wl18xx_acx_rx_rate_stat, rx_frames_per_rates field is an
array, not a number. This means WL18XX_DEBUGFS_FWSTATS_FILE can't be
used to display this field in debugfs (it would display a pointer, not
the actual data). Use WL18XX_DEBUGFS_FWSTATS_FILE_ARRAY instead.
This bug has been found by adding a __printf attribute to
wl1271_format_buffer. gcc complained about "format '%u' expects
argument of type 'unsigned int', but argument 5 has type 'u32 *'".

When a function requests to recover, it would normally abort and will
not send any additional commands to the HW. However, other threads may
not be aware of the failure and could try to communicate with the HW
after a recovery was queued, but before the recovery work began.
Fix this by introducing an intermediate state which is set when recovery
is queued, and modify all state checks accordingly.

Instead of adding more files from the lower drivers into the same
directory in debugfs as wlcore, we now add a subdirectory for the
lower driver. This makes things a bit easier, because we can quickly
see where the debugfs entry is implemented and what is specific to the
lower driver.
