arm64: dts: rockchip: enable NPU on rk3588-tiger
From: Heiko Stuebner <heiko.stuebner@...> Date: Wed, 7 Aug 2024 20:53:59 +0200
Commit-Message
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. Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
