[PATCH v2 0/4] Add CMDQ API for upcoming ISP feature

[Jason-JH.Lin <jason-jh.lin@mediatek.com>]

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

In order to support the upcoming ISP functions, some CMDQ APIs
need to be prepared:
1. cmdq_pkt_mem_move():
   For memory or register value from copy src_addr to dst_addr.
2. cmdq_pkt_poll_addr():
   Extending cmdq_pkt_poll() to support polling the register address
   which doesn't have a subsys id.
3. cmdq_pkt_acquire_event():
   To support mutex_lock protection between GCE threads.

Change in v2:
1. Change the return variable from 'err' to 'ret'.
2. Add more comment and commit message.
3. Drop the last PATCH 5/5 in v1.

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