Provide a soc0 node and reference the same to simplify dts. This also resolves the following warnings when built with W=1: arch/arm/boot/dts/keystone-k2hk-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name arch/arm/boot/dts/keystone-k2l-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name arch/arm/boot/dts/keystone-k2e-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name arch/arm/boot/dts/keystone-k2g-evm.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name arch/arm/boot/dts/keystone-k2g-ice.dtb: Warning (unit_address_vs_reg): Node /soc has a reg or ranges property, but no unit name NOTE: Though we can reformat files by reducing 1 level of indent due to the use of soc0 phandle, we omit that change to prevent un-necessary churn in code base.
