wireless: ath9k-htc: fix possible use after free

'struct struct hif_device_usb' may be freed by
ath9k_hif_usb_disconnect() after

complete(&hif_dev->fw_done);

But 'hif_dev' is still accessed after the line code

This patch fixes the issue by not accessing 'hif_dev'

mac80211: handle power constraint/country IE better

Currently, mac80211 uses the power constraint IE, and reduces
the regulatory max TX power by it. This can cause issues if
the AP is advertising a large power constraint value matching
a high TX power in its country IE, for example in this case:

...
Country: US  Environment: Indoor/Outdoor
    ...
    Channels [157 - 157] @ 30 dBm
    ...
Power constraint: 13 dB
...

What happened here is that our local regulatory TX power is
15 dBm, and gets reduced by 13 dB so we end up with only
2 dBm effective TX power, which is way too low.

Instead, handle the country IE/power constraint IE combined
and restrict our TX power to the max of the regulatory power
and the maximum power advertised by the AP, in this case
17 dBm (= 30 dBm - 13 dB).

Also print a message when this happens to let the user know
and help us debug issues with it.

libertas: set mac control synchronously during init

CMD_MAC_CONTROL is currently sent async to the firmware, and is sent
from the lbs_setup_firmware() path during device init.

This means that device init can complete with commands pending, and
the if_sdio driver will sometimes power down the device (after init)
with this command still pending.

This was causing an occasional spurious command timeout after init,
leading to a device reset.

mwifiex: have same priority for AP and station traffic

Currently AP interface has higher priority over station. Hence
separate entries are created in "adapter->bss_prio_tbl" for these
interfaces and station packet is dequeued only if there is not
packet in queue for AP. It is observed that ping for station
interface doesn't work if heavy traffic is running on AP.

The problem is fixed by having same priority for both the
interfaces. This patch also removes an extra initialisation
for "priv->bss_priority".

vmalloc() the firmware and copy it into a single
page of DMA-coherent memory for the upload.

The advantage is that we don't need DMA memory for
the firmware image that is stored while the driver
is operating, we only need it while uploading.

rt2x00: Unify GPIO register field namings

The various rt2x00 drivers use different methods to name the different
GPIO register fields indicating the GPIO pin value and the fields
indicating the direction.
Start using a unified naming scheme for the GPIO register fields:
- <csr>_VAL<x> for fields indicating the GPIO pin value.
- <csr>_DIR<x> for fields indicating the GPIO pin direction.

rt2x00: Align GPIO register definitions with the datasheets.

Ensure that all active GPIO pins are included in the GPIO register
definitions, nothing more and nothing less.
