mac80211: ath9k: enable adding wireless noise to kernel entropy pool

Browse Source 
This option allows adding the ath9k ADC register output as a source
of randomness into the Linux entropy pool at sufficient quality
random data (at least 10 bits and up to 22 bits of min-entropy for
a 32-bit value).

Fixes FS#1444
