Using the enable_beacon flag allows some simplifications and fixes
some corner cases in beacon handling. This change adds a state
variable for beaconing in ath5k_beacon_config and handles both
enabling and disabling, thus eliminating the need for
ath5k_beacon_disable. We also now configure the beacon when any
of the beacon parameters change, so ath5k_beacon_reconfig is no
longer needed (its mmiowb gets moved to ath5k_beacon_config).
Finally, by locking around the whole config function, we don't
need to worry about clearing the interrupt mask register before
installing the new mask.
The upshot is this correctly disables beaconing when the interfaces
are taken down, it fixes a potential restarting of beaconing
when ath5k_reset() is called, and ensures that updates to the
beacon interval take effect immediately.

Always enable rfkill since the ifdefs in the code is not really worth
the Kconfig option. Also fix a few code style things, and remove the
usage of the ah_gpio[] array so we can remove it later.

This patch introduces initial rfkill support for the ath5k driver
based on rfkill support in the cfg80211 framework.
All rfkill related code is separated into newly created rfkill.c.
Changes to existing code are minimal:
* added a new data structure ath5k_rfkill to the ath5k_softc structure
* inserted calls to HW rfkill init/deinit routines
* ath5k_intr() has been extended to handle AR5K_INT_GPIO interrupts

This patch simplifies the code used to detect when the
self-linked DMA buffer is still in use by hardware, by
checking the hardware's rxdp register instead of looking
at the software buffer list.
