[PATCH v3 10/10] arm64: dts: rockchip: enable NPU on ROCK 5B

[Tomeu Vizoso]

From: Nicolas Frattaroli <nicolas.frattaroli at collabora.com>

The NPU on the ROCK5B uses the same regulator for both the sram-supply
and the npu's supply. Add this regulator, and enable all the NPU bits.
Also add the regulator as a domain-supply to the pd_npu power domain.
