[RESEND, PATCH 0/5] Add CMDQ API for upcoming ISP feature

[Jason-JH.Lin]

From: Jason-jh Lin <jason-jh.lin at mediatek.corp-partner.google.com>

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.
