Hi Matthias,

Rename STATE_IN_BAND_SLEEP_ENABLED to QCA_IN_BAND_SLEEP_ENABLED.
The constant represents a flag (multiple flags can be set at once),
not a unique state of the controller or driver.
Also make the flag an enum value instead of a pre-processor constant
(more flags will be added to the enum group by another patch).
