Subject: [PATCH 07/15] arm64: dts: socfpga: stratix10: move firmware out of soc node

The "soc" node is supposed to have only MMIO children, so move the
firmware/svc node to top level to fix dtc W=1 warnings like:

  socfpga_stratix10.dtsi:625.12-635.5: Warning (simple_bus_reg): /soc@...irmware: missing or empty reg/ranges property

The node should still be instantiated by drivers/of/platform.c, just
like in all other platforms.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
