Yedidya Benshimol 0d91a2bfc3 wifi: iwlwifi: remove struct iwl_trans_ops 
This was needed when we had multiple types of transports. Now we only
have pcie, so there is no need for this ops.
Cleanup the code such as the different trans APIs will call the pcie
function directly, instead of calling the callback,
and remove struct iwl_trans_ops.
