For some client driver, it want to reduce latency between excuting
previous packet command and next packet command, so append jump
command to the end of previous packet and the jump destination
address is the start address of next packet command buffer. Before
next packet exist, the previous packet has no information of where
to jump to, so append nop command first. When next packet exist,
change nop command to jump command. For mediatek drm driver, it
never has next packet, so appending nop command is redundant.
Because cmdq_pkt_finalize() would append nop command, so change
calling cmdq_pkt_finalize() to cmdq_pkt_eoc() to prevent append
redundant nop command.
