mac80211: ath9k: register id table for platform device

Currently the device id in the platform driver is hardcoded to an
id which is specific to AR9130/AR9132 SOCs as it supports only wmac
(wireless mac) of these SOCs. But this needs to be dynamic when we
want to support different wmac of SOCs. So add id_table to driver to
make it extendable to more SOCs.
