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.

I'm not sure we need this property?
The binding states:
"""
This property is intended to only be used for regulators where
software cannot read the state of the regulator.
"""
but the rk860 we use here can report its state if I read the driver
properly.
If that is correct the same "mistake" was done for other RK3588 boards
which enabled the NPU recently.
The diff makes sense compared to other RK3588 boards' recent NPU support
addition so I guess this is fine :)
I am currently unable to test this though but considering that this is
an IP within the SoC which only differs between different boards by its
regulator feeding the controller(s) and that this change looks in sync
with our hardware design, I guess we don't need to wait for me to be
able to test this :)
Same remarks for the next patch in the series.
Cheers,
Quentin

I still have the same remark about regulator-boot-on but this isn't a
blocker per-se.
The Oops I alluded to in my answer to the Jaguar patch is triggered by
making DRM_ACCEL_ROCKET driver built-in instead of as a module. I'm not
sure how much I will debug this on my side, I'll prolly just report this
on the ML in a few hours.
Thanks!

Just for people stumbling over this, the cause is the pm-domains
being on on boot and the iommu after probing disabling the domain.
