toshiba_acpi: Add support for bluetooth toggling through rfkill (v8)
There's been a patch floating around for toshiba_acpi that exports an ad-hoc
/proc interface to toggle the bluetooth adapter in a large number of Toshiba
laptops. I'm not sure if it's still relevant for the latest models, but it is
still required for older models such as my Tecra M3.
This change pulls in the low level Toshiba-specific code from the old patch and
sets up an rfkill device and a polled input device to track the state of the
hardware kill-switch.

It is obviously good for userspace to know up front which
interface modes a given piece of hardware might support (even
if adding such an interface might fail later because of
concurrency issues), so let's make cfg80211 aware of that.
For good measure, disallow adding interfaces in all other
modes so drivers don't forget to announce support for one mode
when they add it.

ath5k: HW code cleanup
* No code changes...
* Split hw.c to multiple files for better maintenance and add some documentation on each file
code is going to grow soon (eeprom.c for example is going to get much stuff currently developed
on ath_info) so it's better this way.
* Rename following functions to maintain naming scheme:
ah_setup_xtx_desc -> ah_setup_mrr_tx_desc
(Because xtx doesn't say much, it's actually
a multi-rate-retry tx descriptor)
ath5k_hw_put_tx/rx_buf - > ath5k_hw_set_tx/rxdp
ath5k_hw_get_tx/rx_buf -> ath5k_hw_get_tx/rxdp
(We don't put any "buf" we set descriptor pointers on hw)
ath5k_hw_tx_start -> ath5k_hw_start_tx_dma
ath5k_hw_start_rx -> ath5k_hw_start_rx_dma
ath5k_hw_stop_pcu_recv -> ath5k_hw_stop_rx_pcu
(It's easier this way to identify them, we also
have ath5k_hw_start_rx_pcu which completes the
set)
ath5k_hw_set_intr -> ath5k_hw_set_imr
(As in get_isr we set imr here, not "intr")
* Move ath5k_hw_setup_rx_desc on ah->ah_setup_rx_desc so we can
include support for different rx descriptors in the future
* Further cleanups so that checkpatch doesn't complain
(only some > 80 col warnings for eeprom.h and reg.h as usual
due to comments)
Tested on 5211 and 5213 cards and works ok.
