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
