[PATCH v4 00/12] support gce on mt8183 platform

[Bibby Hsieh <bibby.hsieh@mediatek.com>]

Changes since v3:
 - fix a typo in dt-binding and dtsi
 - cast the return value to right format

Changes since v2:
 - according to CK's review comment, change the property name and
   refine the parameter
 - change the patch's title
 - remove unused property from dt-binding and dts

Changes since v1:
 - add prefix "cmdq" in the commit subject
 - add dt-binding document for get event and subsys function
 - add fix up tag in fixup patch
 - fix up some coding style (alignment)

MTK will support gce function on mt8183 platform.
  dt-binding: gce: add gce header file for mt8183
  soc: mediatek: cmdq: support mt8183 gce function
  arm64: dts: add gce node for mt8183

Besides above patches, we refine gce driver on those patches.
  soc: mediatek: cmdq: move the CMDQ_IRQ_MASK into cmdq driver data
  soc: mediatek: cmdq: clear the event in cmdq initial flow

In order to enhance the convenience of gce usage, we add new helper
functions and refine the method of instruction combining.
  dt-binding: gce: remove thread-num property
  dt-binding: gce: add binding for gce event property
  dt-binding: gce: add binding for gce subsys property
  soc: mediatek: cmdq: add packet encoder function
  soc: mediatek: cmdq: add polling function
  soc: mediatek: cmdq: add cmdq_dev_get_subsys function
  soc: mediatek: cmdq: add cmdq_dev_get_event function
