soc: mediatek: cmdq: Add parameter shift_pa to cmdq_pkt_jump()
In original design, cmdq_pkt_jump() call cmdq_get_shift_pa() every
time to get shift_pa. But the shift_pa is constant value for each
SoC, so client driver just need to call cmdq_get_shift_pa() once
and pass shift_pa to cmdq_pkt_jump() to prevent frequent function
call.
