[PATCH v4 00/13] support gce on mt6779 platform

[Dennis YC Hsieh]

This patch support gce on mt6779 platform.

Change since v3:
- refine code for local variable usage
- use cmdq error code to consistent with current design
- return error directly after send if error code return
- also modify drm driver which uses cmdq_pkt_wfe api
- add finalize in drm driver

Change since v2:
- rebase onto 5.6-rc1
- remove unnecessary definition
- add clear parameter in wfe api
- separate assign and write_s api
- add jump api instead of finalize in loop
