ath9k: General code scrub 

Replace TRUE/FALSE macros with VALID/INVALID macros.
Follow a consistent variable convention.
Remove unnecessary comments.
Add all RC phy macros into a single enum.
Merge functions into reasonably sized entities.

/*
* Interface definitions for transmit rate control modules for the
* Atheros driver.
*
* A rate control module is responsible for choosing the transmit rate
* for each data frame. Management+control frames are always sent at
* a fixed rate.
*
* Only one module may be present at a time; the driver references
* rate control interfaces by symbol name. If multiple modules are
* to be supported we'll need to switch to a registration-based scheme
* as is currently done, for example, for authentication modules.
*
* An instance of the rate control module is attached to each device
* at attach time and detached when the device is destroyed. The module
* may associate data with each device and each node (station). Both
* sets of storage are opaque except for the size of the per-node storage
* which must be provided when the module is attached.
*
* The rate control module is notified for each state transition and
* station association/reassociation. Otherwise it is queried for a
* rate for each outgoing frame and provided status from each transmitted
* frame. Any ancillary processing is the responsibility of the module
* (e.g. if periodic processing is required then the module should setup
* it's own timer).
*
* In addition to the transmit rate for each frame the module must also
* indicate the number of attempts to make at the specified rate. If this
* number is != ATH_TXMAXTRY then an additional callback is made to setup
* additional transmit state. The rate control code is assumed to write
* this additional data directly to the transmit descriptor.
