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

Commit Message

Chun-Kuang Hu Feb. 15, 2024, 12:49 a.m. UTC

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.
