RK3576 enablement for the mainline rocket NPU driver

A 4-patch RFC series adding Rockchip RK3576 support to the mainline rocket NPU driver (drivers/accel/rocket), against torvalds/master.

Apply with git am *.patch onto a recent mainline tree.

0001  dt-bindings: npu: rockchip,rk3588-rknn-core: add RK3576 (conditional sram-supply)
0002  accel/rocket: look up core clocks by name (fixes clk_bulk .id never set)
0003  accel/rocket: add support for the RK3576 (per-SoC match data + PC_DONE polling)
0004  arm64: dts: rockchip: add RKNN core nodes to rk3576

Status: compile-tested only, no RK3576 hardware. rocket builds clean at W=1, all ten rk3576 board dtbs build, dt_binding_check and CHECK_DTBS pass (including a negative test that sram-supply is rejected on RK3576). Builds on @gahingwoo's Rock 4D bring-up and the dri-devel prior art from Nicolas Frattaroli / Tomeu Vizoso. See the cover letter (0000) for open items.
