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.
