Enable the NPU cores and their mmus and wire up the supply-regulator.
The regulator itself was already defined, but it does not need to be
always on - the npu can control it.


My apologies for the time it took me to review and test this.

I tested with aarch64 defconfig + DRM_ACCEL_ROCKET=m loosely following the instructions from https://docs.mesa3d.org/teflon.html and the script finishes, so I guess that means it works.

I have managed to get an Oops with another defconfig, but that is not related to DT so not a blocker for merging this.

Thus:

Note that I have the same remark about regulator-boot-on property in vdd_npu_s0 I made[1] for Tiger here.
