Subject: [PATCH v1 0/2] firmware: Add MediaTek TinySYS SCMI Protocol

This series adds basic support for the MediaTek TinySYS SCMI Protocol,
found on the MediaTek Dimensity 9200, 9300 and 9400, other than on the
MT8196 Chromebook SoC.

This is used to communicate with the CM_MGR and other MCUs for power
management purposes.
