[PATCH v10 0/7] soc: mediatek: SVS: introduce MTK SVS engine

From: Roger Lu

1. SVS driver uses OPP adjust event in [1] to update OPP table voltage part.
2. SVS driver gets thermal/GPU device by node [2][3] and do device_link_add()
to make sure probe/suspend callback priority.
3. SVS driver gets CPU device by get_cpu_device() and do device_link_add()
to make sure probe/suspend callback priority.
3. SVS dts refers to reset controller [4] to help reset SVS HW.

changes since v9:
- Since MTK SVS is SoC specific driver that doesn't share any code,
move it into Soc specific directory like these.
- Remove unnecessary SVS header file.
- Add mt8192 SVS driver.
- Change linux license to GPL-2.0-only.
- Squash "struct mtk_svs" members into "struct svs_platform"
and remove "struct mtk_svs".
