Subject: [PATCHv3 4/5] wifi: ath9k: ahb: replace id_table with of
Since 2b0996c7646 , all of this platform code became no-op with no OF
replacement. Not only that, there are no users of AHB here. Add an OF
match table that mostly mirrors the original platform device id table.
Use a qca prefix as is done for the only other property: qca,no-eeprom.
Also used qca prefix for ar9530 as the latter seems to be a mistake.
Use qcom, prefix as done with the other ath wireless drivers.
