ath9k: deny new interface addtion on IBSS mode

The present check denies the IBSS interface addtion if we
already have any other vifs. But it fails to deny interface
addition if IBSS was already present.

wl1251: Add support for idle mode

On Nokia N900 the wl1251 consumes the most power when the interface is up
but not associated to access point (that supports PSM). In terms of battery
current consumption, the consumption is ~180 mA higher when the interface is
up but not associated and only ~5 mA higher when associated compared to
interface down and driver not loaded cases.

This patch adds support for the mac80211 idle notifications. Chip is put into
idle very much the same way when entering into PSM by utilizing the Extreme
Low Power (ELP) mode. I.e. idle is entered by setting necessary conditions
in wl1251_ps_set_mode followed by a call to wl1251_ps_elp_sleep.

It seems it is just enough the authorize ELP mode followed by
CMD_DISCONNECT (thanks to Kalle Valo about the idea to use it).
Without disconnect command the chip remains somewhat active and stays
consuming ~20 mA. Idle mode is left by same way than PSM. The wl1251_join
call is used to revert the CMD_DISCONNECT. Without it association to AP
doesn't work when trying second time.

With this patch the interface up but not associated case the battery current
consumption is less than 1 mA higher compared to interface down case.

wl1251: Prepare for idle mode support

RFC for WL1251 idle mode support brought a few issues that are worth to
update before adding the idle mode support.

Since the idle mode can reuse the code that is now used in Power Save Mode
(PSM), the flag psm in struct wl1251 is changed to variable station_mode
to be able to distinguish between PSM and idle modes.

As the station mode is different than the power power save mode command
that is sent to chip, the enum wl1251_cmd_ps_mod values are used only when
communicating with the chip and new enum wl1251_station_mode values are used
inside the driver.

Confusing comment about psm and elp relation is removed since the PSM is
actually activated by putting the chip into Entreme Low Power (ELP) mode.

mwifiex: use IEEE80211_HT_CAP_ macros for 11n cap_info

The hw_dot_11n_dev_cap reported by firmware hw_spec
has different format than the 11n capabilities.
Hence a lot of SET_ and RESET_ bit operation macros
were used to convert the dev_cap format to 11n
capability format. However the locally defined 11n
ht_cap macros are not necessary as we can use
IEEE80211_HT_CAP_ macros directly.

The 32-bit dev_cap bitmap is added as comment to
explain the mapping between firmware and 11n spec.

Some unused macros and unnecessary adapter variables
are also removed.

mac80211: remove the dependency on crypto_blkcipher

The only thing that using crypto_blkcipher with ecb does over just using
arc4 directly is wrapping the encrypt/decrypt function into a for loop,
looping over each individual character.
To be able to do this, it pulls in around 40 kb worth of unnecessary
kernel modules (at least on a MIPS embedded device).
Using arc4 directly not only eliminates those dependencies, it also makes
