[RFC PATCH v2 1/8] dt-bindings: npu: rockchip: add rockchip,rk3576-rknn-core

[Jiaxing Hu]

Document the RK3576 NPU core: add rockchip,rk3576-rknn-core to the
compatible enum.  The RK3576 has no NPU SRAM supply, so make sram-supply
required only for rockchip,rk3588-rknn-core via an allOf/if-then instead
of dropping it from the shared required list (which would have weakened
validation for RK3588).
