ath9k: constify ath_bus_ops structure

Browse Source 
Declare the structure ath_bus_ops as const as it is only passed as an
argument to the function ath9k_init_device. This argument is of type
const struct ath_bus_ops *, so ath_bus_ops structures with this property
can be declared as const.
Done using Coccinelle:

static struct ath_bus_ops i@p = {...};
