arm64: dts: mediatek: mt6795: Create soc bus node and move mmio devices

MMIO devices should be inside of a soc bus node, as it's done for the
vast majority of ARM64 devicetrees, and for almost all MTK devicetrees.
Create a simple-bus soc node and move all devices with a MMIO address
space in there.
