Currently firmware crash dump is printed only if debug is enabled.
Change it so that the crash dump is always printed.
Also move the code from init.c to hif.c.

The benefit from this is that user space can control hardware's power state
by putting interface up and down. This is handy if firmware gets to some
weird state.
The downside will be that putting interface up takes a bit longer,
I was measuring ~500 ms during interface up.

Currently the name of the driver in struct sdio_driver is "ath6kl_sdio",
this is for example what uevent advertises. This is wrong as the module
is named as ath6kl.ko. Change it to "ath6kl" so that the names match.

Use of cfg80211_scan_request is not valid after calling cfg80211_scan_done()
but ath6kl_cfg80211_scan_complete_event() was doing exactly that. Change
the function to call cfg80211_scan_done() last.
This was found during code review, I didn't see any visible problems
due to this bug.

The wpa_supplicant was receiving incorrect frame contents in the
callback function that indicates the status of the frame transmitted.
This patch fixes a missing copy of the frame contents to a local
buffer. The local buffer keeps track of the last sent management frame.

Even though only a single concurrent remain-on-channel operation is
supported, there may be two pending remain-on-channel events (one to
indicate end of a canceled operation and another to indicate start of a
new operation). User space won't be able to distinguish these events
unless unique cookies are used.
The previous behavior resulted in wpa_supplicant getting quite
confused about the driver's offchannel state in various sequences
and this made the P2P state machine behave incorrectly. Use of
more than a single remain-on-channel cookie value fixes this.

When compiling ath6kl for ARM with device tree tree compilation fails
with errors like:
include/linux/of.h: In function 'of_property_read_u32_array':
include/linux/of.h:249:10: error: 'ENOSYS' undeclared
Workaround this by including errno.h from init.c.

In order to allow user space based control of power parameters, we use
available debugfs infrastructure. With these features user can control
power consumption by adjusting various sleep/wake up related parameters.
The feature has been added for testing purposes. All 5 parameters are
mandatory in correct order. They have to be written to the power_params
file. These are:
1) idle_period
2) no_of_pspoll
3) dtim_policy
4) tx_wakeup_policy
5) no_tx_to_wakeup
Example:
echo "200 1 0 1 1" > power_params

In order to allow user space based control of listen interval, we use
available debugfs infrastructure. Listen interval implies how frequently
we want the WLAN chip to wake up and synchronize the beacons in case it
is in sleep mode. The command requires two parameters in the following order:
1) listen_interval_time
2) listen_interval_beacons
The user has to write the listen interval_time (in msecs) and
listen_interval_beacons (in no. of beacons) to the listen_interval file in
ath6kl debug directory.
Example:
echo "30 1" > listen_interval
