arm64: dts: mediatek: add support for MT8370 SoC 



Add the support of the Mediatek MT8370 SoC, a less powerful variant of
MT8390 SoC.
Their main differences are:
- Arm Cortex-A55 cores number (4 vs 6)
- Arm Cortex-A78 core speed (2.0 GHz vs 2.2 Ghz)
- Arm Mali-G57 GPU core number (2 vs 3)

Like MT8390, MT8370 hardware register maps are identical to MT8188.

Note:
The devicetree for MT8370 SoC does not currently contain the needed
overrides to support the Mali GPU integrated into this SoC. This is
scheduled to be done with a later change.
