[PATCH] arm64: dts: rockchip: Enable the NPU on ODROID-M2

[Youngwon Son]

Enable the NPU cores and their IOMMUs on the ODROID-M2 and wire up
the vdd_npu_s0 regulator.

As the regulator is now controlled through the NPU power domain,
remove regulator-always-on. regulator-boot-on is not needed either,
since the RK8602 state can be read back.

Tested with the rocket driver and Mesa Teflon (MobileNet V1).
