Subject: [PATCH 7/9] soc: mediatek: cmdq: Remove cmdq_pkt_finalize() helper function

Because client driver has the information of struct cmdq_client, so
it's not necessary to store struct cmdq_client in struct cmdq_pkt.
cmdq_pkt_finalize() use struct cmdq_client in struct cmdq_pkt, so
client driver use cmdq_pkt_eoc() and cmdq_pkt_nop() to replace
cmdq_pkt_finalize() and this function could be removed.
