e702ba18f2 ath9k_hw: fix endian issues with CTLs on AR9003
Parsing data using bitfields is messy, because it makes endian handling
much harder. AR9002 and earlier got it right, AR9003 got it wrong.
This might lead to either using too high or too low tx power values,
depending on frequency and eeprom settings.
Fix it by getting rid of the CTL related bitfields entirely and use
masks instead.

Change the module parameter name to bt_ch_inhibition from

BT Core to inhibit its activity in channels that interfere
with WiFi activity (and vice versa) if bt_ch_inhibition is enabled

Set module parameter "bt_ch_inhibition=0" will disable the channel

Enabling L1 Active allows to save power if the BIOS / bus driver allows

4352fab5c2 ath5k: Set turbo bit on rf bank 2
* A diff between rfbuffer settings of turbo and non-turbo
 modes indicates there is a bit on bank 2 related to turbo operation
 (it's set on turbo modes). This bit is present on all radios except
 RF5413 that seems to have a completely different bank 2. Also
 since 2317 has the same rf-registers locations with 2425 and
 since the bit exists on 2317 I assume it also exists on 2425/2417).
 So in case we use turbo mode (40MHz) enable it on bank modification.

8aec7af99b ath5k: Support synth-only channel change for AR2413/AR5413
* Add synth-only channel change for AR2413/5413. When we call
 ath5k_reset with a channel ath5k_hw_reset will first try to
 set channel on PHY while PHY is running instead of doing a normal
 full reset. To do this phy_init has to change to implement this
 functionality.

 * Clean up change_channel flag, what it really did was skip PCU
 registers when setting initvals. This is done because on reset
 PCU registers are not affected (except the registers we set
 in pcu init and -due to hw problems- TSF). Use a new skip_pcu
 flag that's not misleading instead. In the future we might use
 that to also skip PCU reset and save us the TSF etc problems
 (needs testing because standard practice is to reset everything).

 * Use fast channel change only when setting channel, and set skip_pcu
 to false only on init. When we reset the card due to DMA or PHY
 problems skip pcu but never do a fast channel change.

This feature is to mitigate the problem of certain 3
stream chips that exceed the PCIe power requirements.An EEPROM flag
controls which chips have APM enabled which is basically read from
miscellaneous configuration element of the EEPROM header.

This workaround will reduce power consumption by using 2 Tx chains for
Single and Double stream rates (5 GHz only).All self generated frames
(regardless of rate) are sent on 2 chains when this feature is
enabled(Chip Limitation).
