[PATCH v3 00/11] Panfrost: Improve and add MediaTek SoCs support

[AngeloGioacchino Del Regno]

Changes in v3:
 - Changed MT8186 bindings to declare only two power domains
 - Added a commit introducing MT8186 specific platform data to
   panfrost_drv

Changes in v2:
 - Add power-domain-names commit from Chen-Yu to the series
 - Kept sram-supply in base schema, overridden for non-MediaTek
 - Added Reviewed-by tags from Steven Price to the driver commits
   (as released in reply to v1's cover letter - thanks!)

This series adds support for new MediaTek SoCs (MT8186/MT8192/MT8195)
and improves MT8183 support: since the mtk-regulator-coupler driver
was picked, it is now useless for Panfrost to look for, and manage,
two regulators (GPU Vcore and GPU SRAM) on MediaTek;

The aforementioned driver will take care of keeping the voltage
relation (/constraints) of the two regulators on its own when a
voltage change request is sent to the Vcore, solving the old time
issue with not working DVFS on Panfrost+MediaTek (due to devfreq
supporting only single regulator).

In the specific case of MT8183, in order to not break the ABI, it
was necessary to add a new compatible for enabling DVFS.
