From: Jason-jh Lin <jason-jh.lin@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>

In order to support the upcoming ISP functions, some CMDQ APIs
need to be prepared:
- cmdq_pkt_mem_move(): for memory or register vaule copy
- cmdq_pkt_poll_addr(): extending cmdq_pkt_poll() to support polling
address of register
- cmdq_pkt_acquire_event(): to support MUTEX_LOCK protection between
GCE threads
- cmdq_get_event()/cmdq_set_event(): to support ISP driver runtime control
some GCE events.


Change in RESEND v1:
1. Remove Change-Id in commit message.
