Subject: [PATCH v8 16/20] soc: mediatek: mtk-cmdq: Remove shift_pa parameter from cmdq_pkt_jump()

Since shift_pa will be stored in the cmdq_mbox_priv structure within
cmdq_pkt, all shift_pa parameters in CMDQ helper APIs can be removed.

Remove the shift_pa parameters from cmdq_pkt_jump(), cmdq_pkt_jump_abs(),
and cmdq_pkt_jump_rel().
