ath9k_hw: move TX/RX gain INI stuff to its own hardware family code
The AR9003 TX/RX gain is currently initialized with the other components, so for now AR9003 does not implment this callback, after hardware bring up we can test moving the TX/RX gain there as well and if it works well move them to its own callback as well. Since all INI stuff is now moved out hw.c no longer needs to include and touch any original INI headers/structs. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.
